S-91290A898 M36 x 160 mm DIN 912, ISO 4762 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional load-bearing capacity with 170,000 psi tensile strength, ideal for high-stress structural connections.
• Superior corrosion resistance from the black-oxide finish, extending service life in harsh industrial environments.
• Precise torque application enabled by the 27mm hex drive and standard socket head, reducing installation errors.
• Reliable thread engagement with M36x4mm coarse thread and Class 5g6g fit, ensuring secure fastening in heavy machinery.
• Optimized strength-to-weight ratio through Class 12.9 alloy steel construction, supporting demanding applications without bulk.
• Enhanced fatigue resistance from Rockwell C37 hardness, minimizing failure risks under dynamic loads.
• Versatile partial threading (84mm min thread length on 160mm body) for adjustable clamping in complex assemblies.

Professional Applications & Engineering Value

Engineered for heavy-duty industrial applications, these M36 socket head cap screws address critical challenges in machinery, automotive, and construction sectors. The black-oxide alloy steel construction combats rust and wear, while the Class 12.9 strength rating and 170,000 psi tensile strength prevent joint failure under extreme vibration or tension. The coarse metric thread (4mm pitch) ensures quick assembly and reduced cross-threading risks, and the 54mm head diameter with 27mm hex drive allows for high-torque installation with standard tools. Ideal for securing large components in presses, molds, or structural frames, these fasteners deliver long-term reliability in environments where precision and durability are non-negotiable.

Specification Summary & Compliance

This socket head cap screw adheres to DIN 912 / ISO 4762 dimensional standards, with Class 5g6g thread fit ensuring precise tolerance for metric coarse threads. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety. The partially threaded design (min 84mm thread on 160mm length) and right-hand thread direction align with international engineering specifications for consistent performance.
