Value Collection A410131 Hex Head Cap Screw M20 X 2.50

Product Description

The VALUE COLLECTION A410131 is a fully threaded hex head cap screw designed for use in metric fastening applications where corrosion resistance is critical. Built from Grade 316 austenitic stainless steel (Grade A4), this screw meets DIN 933 standards, making it a reliable choice for marine, chemical, and industrial environments. It features an M20 x 2.50 thread size with an 80 mm length under head and a 30 mm hex drive. Licensed trades and industrial maintenance personnel install this fastener where stainless steel construction and full thread engagement are required by spec or by environmental conditions.

This cap screw is suited for heavy-duty metric bolting in marine hardware, process piping supports, structural brackets, and industrial equipment assemblies. Grade 316 stainless steel provides strong resistance to chloride-induced corrosion, making it a common selection in coastal, offshore, and chemical processing settings. Each order includes 5 pieces per package, and the minimum order quantity is 1 package. The uncoated finish preserves the natural properties of the stainless steel without any additional surface treatment that could interfere with torque or chemical compatibility.

Compatibility

Designed as a DIN 933 compliant fully threaded hex head cap screw for metric fastening applications requiring M20 x 2.50 thread specifications and Grade 316 stainless steel material.

Installation Notes

Installation should be performed by qualified mechanical or industrial maintenance personnel following applicable torque specifications from engineering drawings or recognized fastener standards. Ensure mating threads are clean and free of debris before installation. When working in environments where galling is a concern with stainless steel fasteners, consider applying an anti-seize compound to the threads prior to assembly. Always use properly sized metric tools to avoid rounding the hex drive.
