Value Collection 42757 M8x1.25 Hex Socket Cap Screw 60mm

Product Description

The VALUE COLLECTION 42757 is a metric hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Featuring an M8 x 1.25 thread size and a 60 mm length under head, this screw is partially threaded and driven with a standard hex (Allen) key. It is manufactured from alloy steel with a black oxide finish coating and carries a material grade of 12.9, indicating exceptional tensile strength suitable for demanding load-bearing connections. Licensed tradespeople and maintenance technicians working in precision mechanical environments rely on this grade for critical joint integrity.

This fastener is suited for use in machinery assembly, equipment maintenance, and fabrication work where a high-strength metric cap screw is required. The partially threaded shank allows for precise clamping force across joined materials. The black oxide finish provides mild corrosion resistance and reduces light reflection on exposed hardware. It conforms to DIN 912 and ISO 898-1 fastener standards, making it appropriate for engineering applications where specification compliance is required.

Key Features

• M8 x 1.25 metric thread size with 60 mm length under head
• Partially threaded shank for controlled clamping in bolted joints
• Alloy steel construction with 12.9 material grade for high tensile strength
• Black oxide finish coating for mild corrosion resistance
• Hex socket drive compatible with standard Allen keys and hex bit drivers
• Conforms to DIN 912 and ISO 898-1 fastener standards

Compatibility

Designed as a standard metric hex socket cap screw conforming to DIN 912 and ISO 898-1, suitable for use in any application requiring an M8 x 1.25 partially threaded alloy steel cap screw at 60 mm length under head.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson familiar with metric fastener torque requirements for Grade 12.9 hardware. Always consult the equipment manufacturer or applicable engineering specification for proper torque values before tightening. Ensure mating threads are clean and free of debris before installation. Do not mix metric and imperial fasteners in the same assembly.
