Professional Applications & Engineering Value

This M4 shoulder screw delivers critical engineering solutions where precise component alignment and rotational stability are paramount. The alloy steel construction with Rockwell C32 hardness ensures dimensional accuracy under load, while the black oxide finish provides essential corrosion protection in manufacturing environments. The standard shoulder profile with controlled tolerances serves as an accurate locating diameter in assemblies, eliminating the need for additional bushings or spacers. These metric shoulder screws are particularly valuable in precision equipment, automation systems, and machinery where socket head design allows for flush mounting and the coarse thread spacing enables rapid maintenance operations without compromising joint integrity.

Specification Summary & Compliance

This precision shoulder screw features M4 x 0.7mm metric threads with Class 5g6g thread fit per ISO standards, ensuring dimensional accuracy and interchangeability. The shoulder diameter maintains tight tolerance control (-0.072 to -0.01 mm) while the shoulder length tolerance ranges from 0 to 0.25 mm for precise application requirements. Manufactured to ISO 7379 specifications, this component is fully RoHS 3 (2015/863/EU) compliant and meets REACH (EC 1907/2006) requirements for industrial use, providing assurance of regulatory compliance and material safety in global markets.
