Value Collection -42757-1 M8x1.25 Hex Socket Cap Screw

Product Description

The VALUE COLLECTION -42757-1 is a partially threaded hex socket cap screw designed for metric fastening applications requiring high tensile strength and corrosion resistance. Built to an M8 x 1.25 thread profile with a 65 mm length under head, this screw is manufactured from alloy steel to a 12.9 material grade, placing it among the highest strength class available for metric fasteners. The black oxide finish provides moderate corrosion resistance and reduces light reflection in precision assemblies. It is driven with a hex socket tool and conforms to DIN 912 and ISO 898-1 standards. Maintenance technicians, machinists, and mechanical assemblers working with metric equipment will find this a direct-fit option for high-load fastening tasks.

This screw is suited for general industrial, mechanical, and machinery assembly applications where a high-strength metric cap screw is specified. The M8 x 1.25 thread size and 65 mm under-head length are commonly used in equipment frames, machine housings, fixture plates, and structural joints. The partial threading allows for accurate clamping force across unthreaded shank sections. Minimum order quantity is 50 pieces, making it appropriate for shop stock or production use.

Key Features

• M8 x 1.25 metric thread with 65 mm length under head
• Grade 12.9 alloy steel construction for high tensile and shear strength
• Black oxide finish for moderate corrosion resistance and clean appearance
• Partially threaded shank for precise clamping in bolted joints
• Hex socket drive for torque application in confined spaces
• Meets DIN 912 and ISO 898-1 fastener standards

Compatibility

Designed as a standard metric replacement or stock fastener for machinery, fixtures, and equipment assemblies specifying an M8 x 1.25 Grade 12.9 hex socket cap screw per DIN 912.

Installation Notes

Installation should be performed by a qualified mechanic or assembler familiar with metric fastener torque specifications for Grade 12.9 hardware. Always verify thread engagement depth and mating material compatibility before installation. Use a calibrated hex socket driver or torque wrench sized for M8 fasteners. Do not exceed the rated material strength of the mating component when applying clamp load.
