Value Collection 534108PR Flat Socket Cap Screw M8x1.25

Product Description

The VALUE COLLECTION 534108PR is a flat socket cap screw manufactured to DIN 7991 standards from 12.9 grade alloy steel with a black oxide finish. Rated at material grade 12.9, this screw delivers high tensile strength suited to demanding fastening applications. The 90-degree flat head profile seats flush with or below the mating surface, eliminating protrusion where clearance is critical. Drive engagement is via a 5 mm hex socket. Overall length is 12 mm with an M8x1.25 metric thread, fully threaded along the entire shank. Machinists, millwrights, and mechanical assemblers commonly install this fastener in precision assemblies where a low-profile, high-strength metric screw is required.

This screw is suited for use in machine frames, fixtures, tooling plates, and mechanical sub-assemblies where a countersunk fastener is needed to maintain a flush surface. The black oxide coating provides moderate corrosion resistance and reduces light reflection on exposed hardware. The fully threaded M8x1.25 shank ensures full thread engagement even in shallow tapped holes. Applications span industrial machinery, automotive tooling, and precision equipment in both shop and field environments.

Key Features

• 12.9 grade alloy steel construction for high tensile and proof load strength
• 90-degree flat head seats flush or countersunk to eliminate surface protrusion
• 5 mm hex socket drive for positive torque engagement with standard Allen keys or hex-bit drivers
• Fully threaded M8x1.25 shank for maximum thread engagement in tapped holes
• Black oxide finish provides moderate corrosion resistance and low-glare appearance
• Conforms to DIN 7991 fastener standard for consistent dimensional compliance

Compatibility

Designed as a DIN 7991-compliant metric flat socket cap screw for use in any application requiring an M8x1.25 fully threaded countersunk fastener with a 5 mm hex socket drive.

Installation Notes

Installation is performed by machinists, millwrights, or mechanical assemblers using a calibrated torque wrench with a 5 mm hex bit. Always ensure the mating tapped hole meets M8x1.25 thread specification and is free of debris before driving the fastener. De-energize and lock out any machinery before accessing fastener locations on live equipment. Do not exceed the torque rating appropriate for 12.9 grade M8 fasteners as specified by applicable engineering standards.
