Value Collection 830848BR M20 Hex Cap Screw 18-8 Stainless

Product Description

The VALUE COLLECTION 830848BR is a metric hex head cap screw designed for general industrial and mechanical fastening applications. It features an M20 x 2.50 thread profile with a 30 mm length under the head and is partially threaded along its shank. Manufactured from 18-8 austenitic stainless steel to Grade A2, this fastener delivers solid corrosion resistance and is suited for environments where mild chemical or moisture exposure is a concern. The 30 mm hex key size provides positive wrench engagement for consistent torque. It conforms to DIN 931 and DIN 933 standards, making it appropriate for use wherever metric DIN fasteners are specified.

This cap screw is used across a wide range of industries including mechanical assembly, structural fabrication, HVAC equipment mounting, plumbing system supports, and general maintenance applications. It is appropriate for both light and medium-duty bolted connections where a metric M20 partially threaded hex fastener is required. Licensed trades including pipefitters, millwrights, and mechanical contractors commonly stock this size. The minimum order quantity is 10 pieces, and each package contains 1 piece.

Installation Notes

Installation of M20 fasteners typically requires a properly sized metric open-end or box wrench, socket, or hex driver. Ensure mating threads are clean and free of debris before assembly. When installing stainless steel fasteners into stainless steel tapped holes, apply an appropriate anti-galling compound to prevent thread seizure during tightening. Always verify thread engagement depth meets the requirements of the applicable design or code specification before final torque.
