Value Collection HC3X08018-050BX Hex Cap Screw M8 Ss

Product Description

The VALUE COLLECTION HC3X08018-050BX is a metric hex head cap screw designed for general mechanical assembly and fastening applications. It features a fully threaded M8 x 1.25 thread form and an 18 mm length under head, conforming to DIN 933 standards. Manufactured from 18-8 austenitic stainless steel (Grade A2), it provides solid corrosion resistance in wet, chemical, or outdoor service environments. A 13 mm hex drive allows installation with standard open-end wrenches, box wrenches, or sockets. This fastener is sold in a minimum order quantity of 50 pieces, making it suitable for production assembly, field service kits, or maintenance stock.

This cap screw is appropriate for use in light-to-medium structural connections, equipment mounting, plumbing fixture assembly, HVAC component attachment, and similar trade applications where a metric fastener with stainless corrosion resistance is required. The bright uncoated finish maintains dimensional tolerances without added coating buildup, which is important in close-tolerance threaded holes. Installers working in food service, marine, or chemical environments commonly specify A2 stainless fasteners to meet corrosion-resistance requirements without galvanic compatibility concerns.

Key Features

• Fully threaded M8 x 1.25 metric thread, 18 mm length under head per DIN 933
• 18-8 austenitic stainless steel, Grade A2 — corrosion resistant in wet and chemical environments
• Bright uncoated finish maintains dimensional tolerances in close-tolerance tapped holes
• 13 mm hex drive accepts standard wrenches and sockets
• Sold in multiples of 50 — suitable for production, service kit stocking, or maintenance inventory

Compatibility

Designed as a standard DIN 933 metric hex head cap screw for use in any application requiring an M8 x 1.25 fully threaded fastener in 18-8 stainless steel.

Installation Notes

Installation is performed with a 13 mm open-end wrench, combination wrench, or socket. Always verify the thread engagement depth in the mating component before torquing. Do not mix stainless steel fasteners with dissimilar metals in submerged or high-conductivity environments without evaluating galvanic corrosion risk. Apply an anti-galling compound or thread lubricant when installing stainless fasteners into stainless tapped holes to prevent thread seizure.
