Value Collection SCXX204020-050BX M4 Hex Socket Cap Screw 50pk

Product Description

The VALUE COLLECTION SCXX204020-050BX is a fully threaded hex socket cap screw in M4 x 0.70 mm thread size with a 20 mm length under head. Manufactured from 316 stainless steel to austenitic Grade A4, this fastener delivers strong corrosion resistance in wet, marine, and chemically exposed environments. The bright uncoated finish maintains dimensional accuracy for close-tolerance applications. Sold in a box of 50, this screw is suited for production assembly, maintenance work, and field repairs where consistent metric hardware is required. Installation uses a standard hex key or Allen driver in the socket drive head.

This fastener is appropriate for use in mechanical assemblies, equipment enclosures, plumbing fixtures, HVAC component mounting, pool equipment hardware, and general trade applications where a metric M4 cap screw is specified. The DIN 912 standard ensures dimensional interchangeability with other DIN 912-compliant hardware. The 316 stainless steel construction makes it a reliable choice in corrosive or moisture-heavy service environments common in plumbing, pool, and coastal HVAC installations.

Installation Notes

Installation is performed by mechanics, plumbers, HVAC technicians, and electricians during equipment assembly or field service. Use the correct metric hex key to avoid rounding the socket drive. Verify thread engagement depth and mating material compatibility before installation, particularly in dissimilar-metal environments where galvanic corrosion may be a concern. Do not overtighten into soft base materials such as aluminum or plastic without appropriate inserts.
