Value Collection 535026PR M4x0.7 Button Socket Cap Screw

Product Description

The VALUE COLLECTION 535026PR is an M4x0.7 button socket cap screw manufactured from alloy steel with a black oxide finish. Built to ISO 7380 and ANSI/ASME B18.3.4M standards, this fully threaded fastener features a low-profile button head driven by a 2.50 mm hex socket. Material grade 12.9 construction delivers high tensile strength with a hardness rating of 38-43 HRC, making it suitable for demanding mechanical assemblies where a flush, rounded head profile is required. The black oxide coating provides mild corrosion resistance and reduces light reflection in finished assemblies. Licensed trades and precision assembly technicians rely on this fastener in applications where standard hex cap screws would protrude beyond acceptable clearance limits.

This screw is suited for use in mechanical, industrial, and manufacturing applications requiring metric fasteners with a button head profile. A 12 mm length under head accommodates moderate material stack thickness, and the right-hand thread direction follows standard installation convention. The M4 thread size fits a wide range of machine components, jigs, fixtures, and equipment panels. Sold individually with a minimum order quantity of 100 units, this fastener is intended for volume use in production or maintenance environments.

Key Features

Compatibility

Designed as an OEM-style metric button socket cap screw for use in standard M4x0.7 threaded applications conforming to ISO 7380 and ANSI/ASME B18.3.4M specifications.

Installation Notes

Installation requires a 2.50 mm hex socket driver; use of an incorrect driver size risks rounding the socket recess. Torque to values appropriate for grade 12.9 M4 fasteners per the applicable engineering specification for the assembly. Ensure mating threads are clean and free of debris before installation. Follow all applicable mechanical assembly codes and equipment manufacturer guidelines when selecting fastener torque and thread engagement depth.
