Value Collection -42729-4 M5x0.80 Hex Socket Cap Screw

Product Description

The VALUE COLLECTION -42729-4 is a partially threaded hex socket cap screw in M5 x 0.80 metric thread, with an 80 mm length under head. Manufactured from alloy steel with a black oxide finish, it meets DIN 912 and ISO 898-1 standards and carries a material grade of 12.9, indicating high tensile strength suitable for demanding mechanical assemblies. The black oxide coating provides mild corrosion resistance and reduces light reflection. This fastener is installed by maintenance technicians, millwrights, and mechanical contractors working on equipment assemblies, jigs, fixtures, and structural mechanical connections.

This screw is suited for applications requiring a high-strength metric fastener with a recessed hex drive. Partial threading is appropriate for clamping applications where thread engagement is needed only at the mating component. Typical install scenarios include machinery frames, HVAC equipment panels, pump housings, and similar industrial or mechanical assemblies where a flush or low-profile fastener head is required.

Key Features

• M5 x 0.80 metric thread with 80 mm length under head
• Partially threaded shank for clamping-style fastening
• Alloy steel construction at material grade 12.9 for high tensile strength
• Black oxide finish for mild corrosion resistance and low reflectivity
• Hex socket drive for torque application in confined spaces
• Meets DIN 912 and ISO 898-1 fastener standards

Compatibility

Designed as a standard DIN 912 metric hex socket cap screw suitable for M5 x 0.80 threaded holes in mechanical, industrial, and equipment assembly applications.

Installation Notes

Install using a correctly sized hex key or socket driver rated for the applied torque. Ensure the mating threaded hole is clean and free of debris before installation. Always verify thread engagement depth meets design requirements for grade 12.9 fasteners. Follow applicable mechanical assembly codes and equipment manufacturer torque specifications for the joint being assembled.
