Value Collection A410129 M20 X 2.50 X 60 Mm Hex Cap Screw 316 Ss

Product Description

The VALUE COLLECTION A410129 is a fully threaded hex head cap screw manufactured from Grade 316 Austenitic Grade A4 stainless steel with an uncoated finish. This metric fastener measures M20 x 2.50 thread size with a 60 mm length under head and a 30 mm hex drive. Grade 316 stainless steel provides elevated corrosion resistance compared to standard 304 grade, making it well suited for demanding environments where moisture, chemicals, or salt exposure are concerns. The DIN 933 standard governs its dimensional and mechanical requirements. This item is sold in a package quantity of 5 pieces.

This cap screw is used in structural, mechanical, and equipment assembly applications where a metric fully threaded fastener with high corrosion resistance is required. Typical install scenarios include marine equipment, food processing machinery, chemical processing equipment, outdoor structural connections, and general industrial fabrication requiring metric hardware. Licensed tradespeople and maintenance professionals working with stainless metric fasteners will find this screw appropriate for a wide range of commercial and industrial applications.

Compatibility

Designed as a standard DIN 933 metric hex head cap screw suitable for use wherever an M20 x 2.50 fully threaded fastener in Grade 316 stainless steel is specified.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or maintenance technician familiar with metric fastener standards. Use a properly sized 30 mm wrench or socket to avoid rounding the hex head. Consult the equipment manufacturer or applicable structural specifications for required clamp load or torque values before installation. Inspect threads on both the screw and mating nut or tapped hole for damage or contamination before assembly to prevent galling, which is common with stainless steel fasteners.
