Professional Applications & Engineering Value
This 316 stainless steel shoulder screw delivers critical engineering value in precision assembly applications where alignment and corrosion resistance are paramount. The UNC coarse thread with Class 3A fit provides superior vibration resistance in machinery, automation systems, and rotating equipment. The knurled hex socket head ensures secure torque transmission during installation, preventing cam-out in high-torque applications. With its 3/16" shoulder diameter and 2 1/4" shoulder length, this fastener precisely spaces components while the right-hand thread design facilitates standard assembly procedures. The combination of 70,000 psi tensile strength and 35,000 psi shear strength makes it ideal for demanding industrial environments where mechanical integrity cannot be compromised.
Specification Summary & Compliance
This shoulder screw features precision 8-32 UNC coarse threads with Class 3A thread fit for superior dimensional accuracy. The shoulder diameter maintains tight tolerances of -0.004" to -0.002" while the shoulder length tolerance ranges from -0.005" to 0.005". Manufactured to exacting standards, this fastener is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting the latest environmental regulations for industrial components.
