The VALUE COLLECTION HC3XX03025-050BX is a fully threaded metric hex head cap screw designed for fastening applications requiring corrosion-resistant hardware. Manufactured from Grade 316 austenitic stainless steel (Grade A4), this fastener offers strong resistance to oxidation, chlorides, and chemical exposure. It carries an M3 x 0.50 thread profile with a 25 mm length under the head and conforms to DIN 933, the international standard for fully threaded hex head screws. The uncoated bright finish leaves the base material exposed, which is appropriate where the alloy itself provides sufficient corrosion protection without additional plating.
This screw is suited for light-duty metric fastening tasks in industrial, marine, food-service, and mechanical assembly environments where stainless steel is specified. Its small M3 diameter makes it common in instrumentation panels, enclosure hardware, thin-gauge brackets, and precision equipment. Licensed tradespeople and assembly technicians working on electrical enclosures, HVAC controls, pool equipment housings, or plumbing access panels will find this fastener appropriate wherever DIN 933 metric hardware is called out in the bill of materials.
Designed as a standard DIN 933 fully threaded hex head cap screw in M3 x 0.50 metric thread, compatible with any M3 x 0.50 metric-threaded nut or tapped hole conforming to metric thread standards.
Install using a 5.5 mm metric hex wrench or appropriately sized socket. Confirm mating threads are clean and free of debris before driving. For stainless steel fasteners in close-tolerance tapped holes, apply an appropriate anti-seize compound to reduce the risk of galling, which is common with austenitic stainless alloys. Always de-energize equipment and follow applicable OSHA lockout-tagout procedures before accessing enclosures or panels where this fastener is being serviced.
