Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 stainless steel construction, ideal for harsh environments and chemical exposure
- Exceptional mechanical strength with 70,000 psi tensile strength and 35,000 psi shear strength for heavy-duty applications
- Precise Class 3A thread fit ensures secure fastening with minimal backlash in high-vibration assemblies
- Knurled socket head design provides enhanced grip and prevents tool slippage during installation
- Standardized shoulder dimensions maintain consistent alignment and spacing in rotating mechanisms
- Broad regulatory compliance including ASME B18.3, RoHS 3, and REACH for global industrial acceptance
- Coarse UNC threading enables quick assembly and disassembly while resisting loosening under dynamic loads
Professional Applications & Engineering Value
This 316 stainless steel shoulder screw delivers critical performance in precision machinery where alignment and corrosion resistance are paramount. The Class 3A thread fit maintains tight tolerances in automated equipment, while the knurled socket head withstands repeated tool engagement without deformation. Engineers specify these UNC threaded shoulder screws for rotating assemblies, bearing mounts, and linkage systems where the precision-ground shoulder acts as a pivot point or spacer. The combination of 70,000 psi tensile strength and full chemical compliance makes these socket head shoulder screws ideal for food processing, marine, and pharmaceutical applications where both mechanical integrity and material safety are required.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with Class 3A thread fit for precision assembly. Features 10-24 UNC coarse threads with right-hand direction, 1/8" hex drive, and standard shoulder dimensions with controlled tolerances. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations for hazardous substance restrictions. Material certification includes Rockwell B79 hardness and mechanical properties verified to meet stated strength values.
