Value Collection 532107PR M8x1.25 Hex Socket Cap Screw 130mm

Product Description

The VALUE COLLECTION 532107PR is a partially threaded hex socket cap screw designed for high-strength mechanical fastening in industrial and manufacturing applications. Manufactured from alloy steel to material grade 12.9, this fastener delivers exceptional tensile and proof load performance where joint integrity is critical. The black oxide finish provides moderate corrosion resistance and reduces surface light reflection. The M8 x 1.25 thread profile and 130 mm length under head suit medium-to-heavy structural assemblies. It is driven by a hex socket tool, allowing high torque application in confined or recessed mounting locations. This fastener conforms to DIN 912 and ISO 898-1 standards, making it suitable for precision-toleranced assemblies that require certified mechanical properties.

This screw is used across general industrial, OEM machinery, tooling fixtures, hydraulic equipment, and mechanical assemblies where high clamp load is required. The partially threaded shank provides a smooth bearing surface in the grip zone, which is preferred in shear-loaded joints or applications where the fastener passes through a clearance hole before engaging a threaded bore. Licensed trade professionals and skilled assemblers working in manufacturing, millwright, and mechanical contracting environments are the primary installers.

Key Features

• Alloy steel construction at material grade 12.9 for maximum tensile strength
• M8 x 1.25 metric thread with 130 mm length under head
• Partially threaded shank for shear-load and clearance-hole applications
• Hex socket drive for high-torque installation in recessed or tight spaces
• Black oxide finish for surface protection and low reflectivity
• Conforms to DIN 912 and ISO 898-1 fastener standards

Compatibility

Designed as a standard DIN 912 metric hex socket cap screw compatible with any M8 x 1.25 threaded bore requiring a grade 12.9 partially threaded fastener at 130 mm length under head.

Installation Notes

Installation is performed using a calibrated hex socket driver or torque wrench with the appropriate M8 hex key bit. Always consult the equipment manufacturer's torque specification for grade 12.9 M8 fasteners, as correct preload is critical to joint integrity. De-energize and lock out all equipment before fastener replacement or assembly. Grade 12.9 fasteners should not be substituted with lower-grade hardware, as the joint design load depends on the rated material grade.
