Value Collection HC3X03040-050BX Hex Cap Screw M3

Product Description

The VALUE COLLECTION HC3X03040-050BX is a fully threaded hex head cap screw conforming to DIN 933 standards. It features an M3 x 0.50 thread size with a 40 mm length under head and a 5.5 mm hex drive. Manufactured from 18-8 austenitic stainless steel to Grade A2, it provides reliable corrosion resistance for general-purpose metric fastening applications. The bright, uncoated finish maintains dimensional accuracy and is compatible with standard metric tooling. Installers in HVAC, plumbing, electrical, and light mechanical assembly specify this fastener where stainless hardware and metric sizing are required.

This screw is suited for residential and commercial applications requiring metric fasteners in corrosion-prone or moisture-exposed environments. The M3 thread size and 40 mm shank length are commonly used in equipment panel assembly, mounting brackets, enclosures, and light-duty structural connections. The fully threaded shank provides maximum thread engagement across the entire fastened length, making it appropriate for through-bolt configurations and thin-material applications. Sold in multiples of 50 per order.

Compatibility

Designed as a DIN 933 compliant metric hex head cap screw suitable for general-purpose M3 threaded fastening applications in equipment assemblies, enclosures, and mounting hardware where stainless steel is specified.

Installation Notes

Installation is performed with a standard 5.5 mm hex wrench or socket. De-energize any electrical equipment and relieve system pressure before accessing fastened components. Apply appropriate thread-locking compound or stainless-compatible anti-seize as required by the application. Avoid over-torquing stainless steel fasteners, as Grade A2 material is susceptible to galling without proper lubrication.
