Value Collection 532109PR M8 X 1.25 Hex Socket Cap Screw

Product Description

The VALUE COLLECTION 532109PR is a metric hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Manufactured from alloy steel to a material grade of 12.9, it delivers exceptional tensile and proof load capacity suited to demanding clamping requirements. The fastener features a 140 mm length under head with partial threading and a black oxide finish coating that provides mild corrosion resistance and a consistent appearance. Installation requires a hex key or Allen driver. This screw is specified by mechanical engineers, maintenance technicians, and machinists working on precision machinery, tooling fixtures, and equipment frames.

This screw is suited for general industrial and OEM assembly work where a high-strength metric fastener with a recessed drive is required. Typical applications include machine tool construction, hydraulic component mounting, jig and fixture fabrication, and structural bolted connections where flush or near-flush head profiles are needed. The M8 x 1.25 thread pitch is the standard coarse pitch for the M8 diameter class, making it broadly compatible with tapped holes and threaded inserts machined to that specification. Packaged in quantities of 1, with a minimum order of 5 units.

Key Features

• Alloy steel construction with 12.9 material grade for high tensile strength
• M8 x 1.25 metric coarse thread, partially threaded along the shank
• 140 mm length under head for deep-reach bolting applications
• Black oxide finish coating for mild corrosion resistance
• Hex socket drive requires standard hex key or Allen driver
• Conforms to DIN 912 and ISO 898-1 fastener standards

Compatibility

Designed as a standard DIN 912 metric socket cap screw for use in any M8 x 1.25 tapped hole or threaded insert conforming to that pitch specification.

Installation Notes

Installation should be performed by a qualified technician or machinist familiar with metric fastener torque requirements for grade 12.9 hardware. Ensure the tapped hole is clean, free of debris, and cut to the correct M8 x 1.25 thread specification before driving the fastener. Do not use an impact driver on precision-tapped holes, as this may damage threads or over-torque the fastener. Consult applicable equipment service documentation or a standard torque table for grade 12.9 M8 fasteners before final tightening.
