Value Collection HC3X03025-050BX M3 Hex Cap Screw 18-8 Ss Din 933

Product Description

The VALUE COLLECTION HC3X03025-050BX is a fully threaded hex head cap screw manufactured from 18-8 austenitic Grade A2 stainless steel with a bright, uncoated finish. This metric fastener uses an M3 x 0.50 thread pitch and measures 25 mm under the head, conforming to DIN 933 standards. The 5.5 mm hex drive allows for precise torquing with a standard metric wrench or socket. It is sold in a minimum order quantity of 50 pieces per package, making it suitable for shop stock, maintenance kits, or production applications. HVAC, plumbing, and electrical professionals rely on stainless fasteners like this for corrosion-resistant panel assembly, equipment mounting, and enclosure work.

This screw is suited for light-duty metric assembly applications where corrosion resistance is a priority. Grade A2 stainless steel performs well in indoor and mildly corrosive outdoor environments, including HVAC equipment enclosures, electrical panel interiors, plumbing fixture brackets, and pool equipment housings. The fully threaded shank provides consistent clamping force across the entire length, which is especially useful in thin-material or through-bolt applications common in trade service work.

Key Features

• M3 x 0.50 metric thread pitch, fully threaded along the entire 25 mm shank length
• 18-8 austenitic Grade A2 stainless steel construction for corrosion resistance
• Bright, uncoated finish — no galvanic coating concerns in stainless-to-stainless assemblies
• 5.5 mm hex drive compatible with standard metric wrenches and sockets
• Conforms to DIN 933 dimensional standard
• Packaged in multiples of 50 for shop stock or bulk service use

Compatibility

Designed as a DIN 933-compliant M3 x 0.50 hex head cap screw suitable for metric-threaded assemblies requiring an 18-8 stainless steel fastener with a fully threaded shank.

Installation Notes

Installation is performed by hand-threading into a pre-tapped M3 x 0.50 metric hole, then tightening with a 5.5 mm hex wrench or socket. Ensure mating threads are clean and free of debris before fastening to prevent galling, which is a known risk with stainless steel fasteners. Anti-seize compound formulated for stainless applications is recommended when fastening into stainless or aluminum tapped holes. Always de-energize equipment and relieve system pressure before accessing panels or enclosures requiring fastener service.
