Value Collection HC1X08040-050BX M8 Hex Cap Screw 50-pack

Product Description

The VALUE COLLECTION HC1X08040-050BX is a metric hex head cap screw designed for general mechanical assembly across industrial, commercial, and trade applications. Sized M8 x 1.25 with a 40 mm length under the head, this fastener is partially threaded and manufactured from 18-8 austenitic stainless steel meeting Grade A2 classification. The 13 mm hex drive accommodates standard wrenches and sockets. Built to DIN 931 dimensional standards, it delivers consistent fitment in metric-threaded assemblies. Each order fulfills a minimum quantity of 50 pieces. Total package weight for the lot is approximately 0.045 pounds per unit basis. Licensed tradespeople and maintenance technicians working with metric fasteners will find this screw suitable for corrosion-exposed installations.

This screw is appropriate for use in residential and light commercial mechanical systems where metric fasteners are specified, including HVAC equipment frames, pump mounts, electrical enclosures, and plumbing fixture hardware. The 18-8 A2 stainless steel construction makes it well suited for damp or mildly corrosive environments such as mechanical rooms, rooftop equipment, and pool equipment areas. Partial threading provides clamping force against a bearing surface rather than threading the full shank, which is the correct configuration for bolted joint applications where a nut or threaded insert is used on the opposite side.

Key Features

• M8 x 1.25 metric thread with 40 mm length under head per DIN 931
• Partially threaded shank for proper bolted-joint clamping in through-bolt applications
• 18-8 austenitic stainless steel, Grade A2 — corrosion resistant in damp and mildly aggressive environments
• 13 mm hex drive accepts standard metric wrenches and sockets
• Minimum order quantity of 50 pieces — suitable for stocking or multi-unit service jobs

Compatibility

Designed as a DIN 931 standard metric hex head cap screw for use in any M8 x 1.25 threaded application requiring a partially threaded fastener in 18-8 stainless steel.

Installation Notes

Installation is performed by qualified tradespeople using standard metric hand tools or power drivers rated for the application torque. Always confirm the mating thread is M8 x 1.25 before installation. Power down or de-energize associated equipment before fastening components on electrical or HVAC assemblies. Do not use in applications requiring full-thread engagement along the entire shank length — select a fully threaded variant for those conditions.
