Value Collection HC3XX08025-050BX M8 Hex Cap Screw 316 Ss

Product Description

The VALUE COLLECTION HC3XX08025-050BX is a fully threaded hex head cap screw manufactured from Grade 316 austenitic stainless steel (A4). It is designed for metric fastening applications where corrosion resistance is a primary requirement. The screw features an M8 x 1.25 thread with a 25 mm length under the head and a 13 mm hex drive. Grade 316 stainless steel provides superior resistance to chlorides and marine environments compared to Grade 304, making this fastener well suited for wet, chemical, or saltwater-exposed assemblies. Licensed tradespeople and facilities maintenance professionals install this type of fastener in industrial and commercial settings.

This fastener is used in a wide range of metric applications including HVAC equipment assemblies, plumbing fixtures, pump housings, pool and aquatic equipment, and general industrial fabrication. The fully threaded shank allows engagement along the full length of the fastener, which is beneficial in thin-material and close-tolerance joints. This item is sold in a minimum order quantity of 50 pieces, making it appropriate for shop stock, service vehicles, or production assembly operations.

Compatibility

Designed as a standard DIN 933 fully threaded hex head cap screw for metric M8 x 1.25 applications. Suitable for use wherever a Grade 316 stainless A4 fastener meeting DIN 933 dimensions is specified.

Installation Notes

Installation is performed by millwrights, pipefitters, HVAC technicians, or general maintenance tradespeople using standard metric hand tools or power drivers with a 13 mm hex socket. Verify thread engagement depth and mating material compatibility before installation, particularly in dissimilar-metal assemblies where galvanic corrosion may be a concern. Follow applicable mechanical codes and equipment manufacturer torque specifications for the assembly. Anti-seize compound is commonly applied to stainless fasteners to prevent galling during installation and future removal.
