Value Collection HC1X12080-025BX M12 Hex Cap Screw 18-8 Ss

Product Description

The VALUE COLLECTION HC1X12080-025BX is a metric hex head cap screw manufactured from 18-8 austenitic stainless steel, Grade A2. It features an M12 x 1.75 thread with a nominal length under head of 80 mm and a 19 mm hex drive. The partially threaded shank follows DIN 931 dimensional standards, making it a direct drop-in for applications requiring a recognized international fastener specification. The 18-8 stainless steel construction provides corrosion resistance suitable for use in wet, humid, or chemically exposed environments. Licensed tradespeople and mechanical contractors working on equipment assemblies, pipe supports, and structural connections will find this fastener appropriate for both indoor and outdoor service conditions.

This screw is used in metric fastener applications across commercial and industrial mechanical systems, including HVAC equipment frames, pump and motor mounting, piping supports, and general equipment assembly. Its partial threading leaves a smooth bearing surface on the shank, which is preferred in bolted joints where shear load distribution and clamp load accuracy are important. The DIN 931 standard ensures dimensional interchangeability with other DIN-compliant hardware. This fastener is sold with a minimum order quantity of 5 pieces.

Key Features

• M12 x 1.75 metric thread with 80 mm length under head per DIN 931
• Partially threaded shank for accurate shear load transfer in bolted joints
• 18-8 austenitic stainless steel, Grade A2 — corrosion-resistant for wet and outdoor environments
• 19 mm hex drive compatible with standard metric wrenches and sockets
• DIN 931 dimensional standard ensures interchangeability with metric-compliant hardware

Compatibility

Designed as a DIN 931-compliant metric hex head cap screw for use in any M12 x 1.75 threaded hole requiring a partially threaded fastener in stainless steel.

Installation Notes

Installation is performed by mechanical contractors or maintenance technicians using a 19 mm open-end, box-end, or socket wrench. Always ensure the mating threaded hole or nut meets the same metric thread specification before installation. Do not mix metric and unified-thread hardware. For structural or pressure-retaining joints, consult applicable codes and engineering specifications for proper torque and preload requirements.
