Value Collection 643142PR Hex Head Cap Screw M12 X 1.75

Product Description

The VALUE COLLECTION 643142PR is a metric hex head cap screw engineered for general-purpose fastening in mechanical assemblies, structural connections, and equipment fabrication. This fully threaded fastener meets DIN 933 and ISO 4017 standards, confirming dimensional and mechanical compliance for applications where spec-traceable hardware is required. The M12 x 1.75 thread and 80 mm length under head suit a wide range of through-bolt and clearance-hole configurations. Grade 8.8 steel delivers a balance of tensile strength and ductility appropriate for medium-to-high-load joints. The bright, uncoated finish keeps the fastener ready for as-installed use or field coating where corrosion protection is applied separately.

This screw is suited for industrial maintenance, OEM equipment assembly, construction fabrication, and mechanical repair work. The fully threaded shank allows engagement along the entire bolt length, which is useful when clamping thin materials or when thread engagement depth varies by application. Tradespeople working in HVAC equipment mounting, plumbing fixture support, electrical panel framing, and general mechanical installations will find this screw applicable across a broad range of tasks where metric hardware is specified.

Key Features

• M12 x 1.75 thread with 80 mm length under head for medium-length through-bolt applications
• Grade 8.8 steel construction provides reliable tensile and yield strength for structural fastening
• Fully threaded shank per DIN 933 and ISO 4017 for consistent dimensional compliance
• 19 mm hex drive size compatible with standard metric wrenches and sockets
• Bright, uncoated finish for bare-metal installations or field-applied corrosion protection

Compatibility

Designed as a metric hex head cap screw replacement or new-installation fastener for any application specifying an M12 x 1.75 x 80 mm fully threaded bolt to DIN 933 or ISO 4017 standards.

Installation Notes

Installation is performed with a 19 mm open-end, box, or socket wrench. Torque to the value specified by the equipment manufacturer or relevant structural engineering specification for Grade 8.8 M12 fasteners. Always de-energize or depressurize the assembly before removing or replacing structural fasteners. Do not substitute this uncoated fastener in environments requiring corrosion-resistant hardware without applying an appropriate coating or selecting a rated alternative.
