Screw standardization is a method of streamlining material procurement, improving production line efficiency, and stabilizing quality by adopting common standards such as JIS and ISO to narrow down the parts used. This provides a wide range of practical benefits, including reducing parts inventory, cutting down on ordering mistakes, and lowering the risk of fastening defects.<\/p>\n<\/div>\n<div class=\"el-p\">\n<p dir=\"auto\">This article provides a detailed explanation of the basic concepts and practical processes of &#8220;screw standardization&#8221; for technical staff, production control, quality assurance, and procurement personnel in manufacturing. By presenting key points for implementation, step-by-step procedures, and case studies of cost optimization using procurement in Vietnam, we aim to support your company&#8217;s productivity improvement and cost reduction.<\/p>\n<\/div>\n<div class=\"el-h3\">\n<h3 dir=\"auto\" data-heading=\"Specific Benefits of Screw Standardization\">Specific Benefits of Screw Standardization<\/h3>\n<\/div>\n<div class=\"el-h4\">\n<h4 dir=\"auto\" data-heading=\"Cost Reduction and Inventory Optimization\">Cost Reduction and Inventory Optimization<\/h4>\n<\/div>\n<div class=\"el-p\">\n<p dir=\"auto\">By narrowing down the parts used through screw standardization, it becomes possible to optimize order lots. This not only reduces purchasing costs but also significantly cuts down on warehouse space and management man-hours by decreasing the variety of inventory. It mitigates the risk of excess inventory, which is common in high-mix, low-volume production, and leads to improved cash flow.<\/p>\n<\/div>\n<div class=\"el-h4\">\n<h4 dir=\"auto\" data-heading=\"Quality Stabilization and Prevention of Fastening Defects\">Quality Stabilization and Prevention of Fastening Defects<\/h4>\n<\/div>\n<div class=\"el-p\">\n<p dir=\"auto\">By standardizing torque control and tolerances based on common standards (JIS\/ISO), the fastening strength of screws can be consistently maintained at a certain level. Establishing work procedure manuals with unified torque values helps prevent fastening defects and rework, reducing the burden on the quality assurance department.<\/p>\n<\/div>\n<div class=\"el-h4\">\n<h4 dir=\"auto\" data-heading=\"Lead Time Reduction and Procurement Efficiency\">Lead Time Reduction and Procurement Efficiency<\/h4>\n<\/div>\n<div class=\"el-p\">\n<p dir=\"auto\">Standardized parts can be arranged immediately by suppliers, significantly shortening procurement lead times. Furthermore, sharing common standard specifications among suppliers reduces communication costs in ordering operations and cuts down on man-hours for order mistakes and specification confirmation tasks.<\/p>\n<\/div>\n<div class=\"el-h3\">\n<h3 dir=\"auto\" data-heading=\"Explanation of Key Points in Screw Standards and Technical Elements\">Explanation of Key Points in Screw Standards and Technical Elements<\/h3>\n<\/div>\n<div class=\"el-h4\">\n<h4 dir=\"auto\" data-heading=\"Main Standards (JIS B 0209 \/ ISO 68-1)\">Main Standards (JIS B 0209 \/ ISO 68-1)<\/h4>\n<\/div>\n<div class=\"el-p\">\n<p dir=\"auto\">Metric screws are the most commonly used standard in the manufacturing industry, with JIS B 0209 (Japanese Industrial Standards) and ISO 68-1 (International Organization for Standardization) being representative. There are two types: coarse thread (larger pitch) and fine thread (smaller pitch). Coarse thread screws are highly versatile, while fine thread screws are suitable for preventing vibration and loosening.<\/p>\n<\/div>\n<div class=\"el-p\">\n<p dir=\"auto\">Key checkpoints when selecting standards:<\/p>\n<\/div>\n<div class=\"el-ul\">\n<ul class=\"has-list-bullet\">\n<li dir=\"auto\" data-line=\"0\"><strong>Outer Diameter and Pitch Suitability<\/strong>: Consider strength and loosening prevention effects according to the usage environment.<\/li>\n<li dir=\"auto\" data-line=\"2\"><strong>Material &amp; Surface Treatment<\/strong>: Requirements for corrosion resistance (stainless steel\/plating, etc.) and load-bearing capacity.<\/li>\n<li dir=\"auto\" data-line=\"4\"><strong>Compatibility Check<\/strong>: Affinity with existing tools and on-site processes.<\/li>\n<li dir=\"auto\" data-line=\"6\"><strong>Cost Comparison<\/strong>: Balance between unit price for bulk procurement and storage costs for small-lot procurement.<\/li>\n<\/ul>\n<\/div>\n<div class=\"el-h4\">\n<h4 dir=\"auto\" data-heading=\"Torque Control and Tolerance (Precision Class)\">Torque Control and Tolerance (Precision Class)<\/h4>\n<\/div>\n<div class=\"el-p\">\n<p dir=\"auto\">To stabilize fastening quality, proper torque control and screw tolerance management are essential. The torque value can be calculated using the following basic formula:<\/p>\n<\/div>\n<div class=\"el-blockquote\">\n<blockquote dir=\"auto\"><p><strong>T = K \u00d7 D \u00d7 P<\/strong><\/p><\/blockquote>\n<\/div>\n<div class=\"el-ul\">\n<ul class=\"has-list-bullet\">\n<li dir=\"auto\" data-line=\"0\"><strong>T (Fastening Torque)<\/strong>: N\u00b7m<\/li>\n<li dir=\"auto\" data-line=\"2\"><strong>K (Friction Coefficient)<\/strong>: Friction coefficient of the thread and seating surface (generally 0.15 to 0.20)<\/li>\n<li dir=\"auto\" data-line=\"4\"><strong>D (Nominal Diameter)<\/strong>: mm<\/li>\n<li dir=\"auto\" data-line=\"6\"><strong>P (Clamping Force\/Preload)<\/strong>: N<\/li>\n<\/ul>\n<\/div>\n<div class=\"el-p\">\n<p dir=\"auto\">The friction coefficient varies depending on the presence of lubricants and surface treatment, so it is important to set the K value based on actual measurement data from the field.<\/p>\n<\/div>\n<div class=\"el-p\">\n<p dir=\"auto\">Additionally, by utilizing ISO precision classes (e.g., 6H\/6g), the tolerance of screw and nut components can be managed. Generally, &#8220;6H\/6g&#8221; indicates a medium level of precision and is optimal for mass-produced items, but for high-precision applications, selecting &#8220;4H\/4g&#8221; can minimize clearance and improve fastening rigidity.<\/p>\n<\/div>\n<div class=\"el-h3\">\n<h3 dir=\"auto\" data-heading=\"Implementation Steps and Practical Process for Screw Standardization\">Implementation Steps and Practical Process for Screw Standardization<\/h3>\n<\/div>\n<div class=\"el-h4\">\n<h4 dir=\"auto\" data-heading=\"Visualize Usage Frequency and Defect Data through Current State Analysis\">Visualize Usage Frequency and Defect Data through Current State Analysis<\/h4>\n<\/div>\n<div class=\"el-ul\">\n<ul class=\"has-list-bullet\">\n<li dir=\"auto\" data-line=\"0\">Extract screw usage data from ERP or production management systems to visualize the usage amount for each type.<\/li>\n<li dir=\"auto\" data-line=\"2\">Identify locations prone to fastening trouble based on defect analysis reports.<\/li>\n<\/ul>\n<\/div>\n<div class=\"el-h4\">\n<h4 dir=\"auto\" data-heading=\"Select Optimal Standards to Balance In-house Products and Customer Requirements\">Select Optimal Standards to Balance In-house Products and Customer Requirements<\/h4>\n<\/div>\n<div class=\"el-ul\">\n<ul class=\"has-list-bullet\">\n<li dir=\"auto\" data-line=\"0\">Evaluate the suitability of JIS\/ISO standards and finalize requirements for outer diameter, pitch, and material.<\/li>\n<li dir=\"auto\" data-line=\"2\">Collaborate with the design department to conduct fastening tests on prototypes and verify the suitability of the standards.<\/li>\n<\/ul>\n<\/div>\n<div class=\"el-h4\">\n<h4 dir=\"auto\" data-heading=\"Establish an Internal System by Defining Responsibilities and Creating Workflows\">Establish an Internal System by Defining Responsibilities and Creating Workflows<\/h4>\n<\/div>\n<div class=\"el-ul\">\n<ul class=\"has-list-bullet\">\n<li dir=\"auto\" data-line=\"0\">Clarify the scope of responsibility for purchasing, design, production, and quality departments using a RACI chart.<\/li>\n<li dir=\"auto\" data-line=\"2\">Establish a standardization project team and set up regular review meetings.<\/li>\n<\/ul>\n<\/div>\n<div class=\"el-h4\">\n<h4 dir=\"auto\" data-heading=\"Develop Training Programs and Standard Work Manuals\">Develop Training Programs and Standard Work Manuals<\/h4>\n<\/div>\n<div class=\"el-ul\">\n<ul class=\"has-list-bullet\">\n<li dir=\"auto\" data-line=\"0\">Create torque control procedure manuals and tolerance management checklists.<\/li>\n<li dir=\"auto\" data-line=\"2\">Conduct workshops for operators to check their understanding of the standardization procedures.<\/li>\n<\/ul>\n<\/div>\n<div class=\"el-h4\">\n<h4 dir=\"auto\" data-heading=\"Evaluate KPIs through Pilot Line Operation\">Evaluate KPIs through Pilot Line Operation<\/h4>\n<\/div>\n<div class=\"el-ul\">\n<ul class=\"has-list-bullet\">\n<li dir=\"auto\" data-line=\"0\">Set KPIs such as lead time reduction rate, defect rate improvement, and inventory turnover rate.<\/li>\n<li dir=\"auto\" data-line=\"2\">Quantitatively evaluate the results of the pilot implementation and identify areas for improvement.<\/li>\n<\/ul>\n<\/div>\n<div class=\"el-h4\">\n<h4 dir=\"auto\" data-heading=\"Continuous Improvement and Review through the PDCA Cycle\">Continuous Improvement and Review through the PDCA Cycle<\/h4>\n<\/div>\n<div class=\"el-ul\">\n<ul class=\"has-list-bullet\">\n<li dir=\"auto\" data-line=\"0\">Share improvement progress in monthly reviews and devise solutions for issues.<\/li>\n<li dir=\"auto\" data-line=\"2\">Reflect improvements in OJT and manual updates, and continue training.<\/li>\n<\/ul>\n<\/div>\n<div class=\"el-h3\">\n<h3 dir=\"auto\" data-heading=\"Cost Optimization by Utilizing Procurement in Vietnam\">Cost Optimization by Utilizing Procurement in Vietnam<\/h3>\n<\/div>\n<div class=\"el-p\">\n<p dir=\"auto\">With the local procurement service provided by Ohta Vietnam, it is possible to directly source standardized screws compliant with JIS\/ISO standards from within Vietnam.
