Value Collection HC3X03020-050BX M3 Hex Cap Screw Din 933

Product Description

The VALUE COLLECTION HC3X03020-050BX is a metric hex head cap screw designed for use in applications requiring corrosion-resistant fastening. Manufactured from 18-8 austenitic stainless steel (Grade A2), this fully threaded screw meets DIN 933 standards and is supplied with a bright, uncoated finish. The screw features an M3 x 0.50 thread and a 20 mm length under head, making it well suited for light-duty mechanical assemblies, panel mounting, and equipment fabrication where a standard metric fastener is required. Installed using a 5.5 mm hex wrench or socket.

This fastener is used across a wide range of trade and industrial applications including HVAC equipment assembly, electrical enclosure mounting, plumbing fixture installation, and general mechanical fabrication. Its stainless steel construction resists rust and mild chemical exposure, making it appropriate for both indoor and outdoor service environments. The fully threaded shank provides maximum thread engagement across the full 20 mm length, which is especially useful in thin-material or through-bolt applications.

Compatibility

Designed as a standard DIN 933 metric hex head cap screw suitable for M3 x 0.50 threaded holes in metal, plastic, and composite assemblies across HVAC, electrical, plumbing, and general industrial applications.

Installation Notes

Install using a 5.5 mm hex wrench or socket driver. Ensure mating threads are clean and free of debris before driving the fastener. Stainless steel fasteners are susceptible to galling — apply an appropriate anti-seize compound when torquing into stainless or aluminum threaded holes. Power down any equipment before accessing panels or enclosures requiring fastener service.
