Value Collection MKCS04C0509MBPKG M4x0.7 Socket Cap Screw 25pk

Product Description

The VALUE COLLECTION MKCS04C0509MBPKG is a partially threaded socket cap screw with an M4x0.7 thread size and a 50 mm length under head. It is manufactured from alloy steel to material grade 12.9, indicating a high-strength fastener suitable for demanding mechanical assemblies. The finish is a zinc-blue trivalent chromate coating, which provides corrosion resistance while meeting RoHS and REACH compliance requirements. The drive type is hex with a 3 mm drive size, fitting a standard hex key or Allen wrench. This screw is sold in a package of 25 and is commonly installed by maintenance technicians, millwrights, and mechanical contractors working on HVAC equipment, pump assemblies, and industrial machinery.

This fastener is suited for applications requiring a high-strength cap screw in metric sizing, including equipment panel fastening, motor mounting, bracket assembly, and general mechanical component attachment in both residential and light commercial trade environments. The partial threading allows for a smooth shank section beneath the head, which is useful when a clamping force across an unthreaded interface is needed. Conformance to DIN 912 and ISO 4762 standards ensures dimensional consistency across production runs.

Key Features

• M4x0.7 coarse right-hand thread with 50 mm length under head
• Alloy steel construction at material grade 12.9 for high tensile strength
• Partially threaded shank for clamping across unthreaded interfaces
• Zinc-blue trivalent chromate finish for corrosion resistance and RoHS/REACH compliance
• Hex drive with 3 mm drive size for standard Allen key installation
• Meets DIN 912 and ISO 4762 fastener standards

Compatibility

Designed as a standard metric socket cap screw conforming to DIN 912 and ISO 4762, suitable for use in any mechanical assembly requiring an M4x0.7 partially threaded cap screw at 50 mm length under head.

Installation Notes

Installation is performed using a 3 mm hex key or Allen wrench. Ensure mating threads are clean and free of debris before driving. Do not exceed the torque capacity of the grade 12.9 alloy steel fastener as determined by the equipment manufacturer. Power down or de-energize any equipment before accessing fastener locations on electrical enclosures or motor assemblies.
