Professional Applications & Engineering Value
Engineered for demanding industrial environments, these M4 socket head cap screws provide critical vibration resistance where traditional fasteners fail. The permanent nylon patch thread locker creates a chemical bond that maintains clamping force despite continuous shock and vibration, eliminating the need for secondary locking devices. Manufactured from black-oxide alloy steel, these metric socket screws deliver exceptional 170,000 psi tensile strength while the coarse M4 x 0.7mm thread profile ensures rapid installation in production environments. The combination of Rockwell C37 hardness and temperature-stable locking performance (-70° to 250°F) makes these fasteners ideal for automotive assemblies, heavy machinery, and precision equipment where reliability cannot be compromised.
Specification Summary & Compliance
These socket head cap screws feature precision Class 5g6g thread fit according to ISO metric standards with M4 x 0.7mm coarse pitch threading and 12mm fully threaded length. Manufacturing conforms to DIN 912 ISO 4762 dimensional specifications. Compliance includes RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant certifications, ensuring environmental regulatory adherence for global industrial applications.
