A concise guide to head diameters, heights, and driver sizes for various thread pitches is hosted by Metric & Multistandard Components.
Using JIS B 1188 PDF offers several benefits, including:
: Since the washers are captive, they cannot be forgotten or lost during maintenance.
Often referred to as or double-washer screws , these specialized fasteners are designed for efficiency in assembly lines. For engineers, procurement officers, and quality control professionals looking for the specific dimensions, material requirements, and mechanical properties, finding a reliable JIS B 1188 PDF is essential. What is the JIS B 1188 Standard?
For those who want to access the full text of the standard, a JIS B 1188 PDF is available for download from various sources, including the Japanese Standards Association (JSA) website. The PDF document provides detailed information on the standard, including the specifications, testing methods, and inspection criteria.
A screw meeting the JIS B 1188 standard generally includes the following defining features:
JIS B 1188 is the Japanese Industrial Standard for cross-recessed head screws with captive washers , commonly known as "Sems" screws
The standard includes detailed tables for thread sizes from M2 up to M8, covering head diameter (dk), head height (k), cross-recess dimensions, various washer dimensions (D1, t), and the important 'a' dimension—the length of the unthreaded shank from the washer to the start of full threads.
For captive washer screw assemblies, the following international standards are relevant:
: Sourcing exact head heights and slot dimensions for 3D designs.
