Value Collection A410127 M20 Hex Cap Screw 316 Ss Din 933

Product Description

The VALUE COLLECTION A410127 is a fully threaded hex head cap screw manufactured to DIN 933 standards in Grade 316 austenitic stainless steel (A4). The M20 x 2.50 thread profile and 40 mm length under head make this screw suitable for structural and mechanical fastening applications where corrosion resistance is a primary requirement. The 30 mm hex drive allows engagement with standard hex sockets or wrenches. Grade 316 stainless steel provides enhanced resistance to chlorides and oxidizing environments compared to Grade 304. Sold in a package of 5 pieces per the listed package quantity.

This fastener is used in marine, chemical processing, food service, and outdoor structural applications where exposure to moisture, salt, or corrosive media demands a corrosion-resistant alloy. Metric thread sizing and DIN 933 conformance make it appropriate for machinery assembly, equipment fabrication, and maintenance applications that specify metric hardware. Installers in plumbing, HVAC, and industrial maintenance commonly use this fastener when joining flanged components, brackets, or equipment frames in corrosive environments.

Installation Notes

Installation should be performed by qualified tradespeople using calibrated metric sockets or wrenches sized for the 30 mm hex. Apply appropriate thread lubricant or anti-seize compound when joining stainless steel to stainless steel components to prevent galling. Follow applicable equipment manufacturer torque specifications and relevant fastener standards when determining final tightening values. Inspect threads and mating surfaces for contamination before assembly.
