Value Collection MP42759 M8x1.25 Hex Socket Cap Screw

Product Description

The VALUE COLLECTION MP42759 is a metric hex socket cap screw designed for precision fastening applications in mechanical assemblies, tooling, and structural connections. Sized at M8 x 1.25 with an 80 mm length under head, this screw features a partially threaded shank, which provides better clamping force and reduces the risk of thread galling in through-bolt applications. Manufactured from alloy steel to material grade 12.9, it delivers high tensile strength suited to demanding industrial environments. The black oxide finish provides mild corrosion resistance and a low-reflectance appearance. Installation requires a hex key or Allen drive.

This screw is appropriate for use in general industrial, manufacturing, and maintenance environments where a high-strength metric fastener is required. Partially threaded M8 cap screws are commonly used in machine frames, jigs, fixtures, and equipment assemblies that require precise clamp load and repeatable torque. The 12.9 material grade makes this screw suitable for high-stress joints where standard-grade fasteners would be inadequate. Sold in minimum order quantities of 25 pieces per order.

Key Features

• M8 x 1.25 thread size with 80 mm length under head
• Partially threaded shank for improved clamping and shear resistance
• Alloy steel construction, material grade 12.9 for high tensile strength
• Black oxide finish for mild corrosion protection and low-reflectance surface
• Hex socket (Allen) drive for high torque input in confined spaces
• Meets DIN 912 and ISO 898-1 fastener standards

Compatibility

Designed as a DIN 912 and ISO 898-1 compliant M8 x 1.25 hex socket cap screw suitable for metric-threaded applications requiring a grade 12.9 alloy steel fastener.

Installation Notes

Installation should be performed using a properly sized hex key or Allen wrench matched to the socket drive. Apply torque according to the applicable fastener specification for grade 12.9 M8 hardware. Inspect mating threads for damage or contamination before assembly. Follow applicable machinery safety lockout and tagout procedures before fastening or removing hardware in powered equipment.
