Value Collection SCX203040-050BX M3x0.5 Socket Cap Screw 40mm

Product Description

The VALUE COLLECTION SCX203040-050BX is an M3 x 0.50 metric hex socket cap screw with a 40 mm length under head, manufactured from 18-8 austenitic stainless steel (Material Grade A2) with a bright uncoated finish. Partially threaded along the shank, this fastener is driven with a hex key and conforms to DIN 912 standards. It is suited for precision mechanical assemblies where corrosion resistance and consistent thread engagement are required. The package contains 50 screws, making it appropriate for production quantities and service kits alike.

This screw is used across a wide range of light mechanical, HVAC, plumbing, and electrical enclosure applications where an M3 metric thread is specified. The DIN 912 standard ensures dimensional consistency with metric hardware sourced from multiple suppliers. Typical installations include equipment panels, motor mounting brackets, control enclosures, and other assemblies calling for a compact, corrosion-resistant cap screw. The partially threaded shank allows for secure clamping between joined components when the thread engages only the receiving piece.

Key Features

Compatibility

Designed as an OEM-style replacement or service stock hex socket cap screw for any application specifying an M3 x 0.50 metric thread, 40 mm length under head, per DIN 912.

Installation Notes

Installation is performed by mechanical technicians or field service professionals using a correctly sized hex key or hex bit driver. Always verify thread engagement in the receiving component before applying torque to avoid cross-threading. Do not mix with non-stainless hardware in assemblies where galvanic corrosion could be a concern. Follow applicable equipment manufacturer torque specifications for M3 fasteners.
