• Enhanced durability and wear resistance from the black oxide finish, extending service life.
• High tensile strength of 70,000 psi ensures reliable performance under heavy loads.
• Precise alignment and reduced wear with a 2 1/4" shoulder length and standard shoulder fit.
• Secure and non-slip installation thanks to the knurled head and 3/8" hex drive.
• Consistent thread engagement with Class 2A UNC coarse threads for easy assembly.
• Compliance with RoHS 3 and REACH ensures environmental and safety standards are met.

Professional Applications & Engineering Value

This 3/4"-10 UNC shoulder screw is engineered to address critical alignment and load-bearing challenges in precision industrial applications. The 18-8 stainless steel material provides excellent corrosion resistance, while the black oxide finish adds an extra layer of protection against wear and oxidation. The 2 1/4" shoulder length acts as a precise pivot or spacer in machinery, reducing friction and preventing component misalignment. With a 70,000 psi tensile strength and 35,000 psi shear strength, it reliably supports heavy-duty operations in automotive, aerospace, and manufacturing equipment. The socket head with hex drive allows for tight installations in confined spaces, making it a versatile choice for engineers seeking durability and precision.

Specification Summary & Compliance

This shoulder screw features Class 2A thread fit with UNC coarse threads for consistent performance. Key dimensions include a shoulder diameter of 3/4" (tolerance: -0.004" to -0.002") and shoulder length of 2 1/4" (tolerance: -0.005" to 0.005"), ensuring precise engineering fits. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting industry standards for safety and environmental responsibility.
