S-97345A461 10-32 ASME B18.3 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 Stainless Steel construction, ideal for harsh industrial environments and chemical exposure.
• Exceptional mechanical strength offering 70,000 psi tensile strength and 35,000 psi minimum shear strength for reliable, heavy-duty load-bearing applications.
• Precise Class 3A thread fit ensures tight, secure fastening with minimal backlash, enhancing assembly accuracy and vibration resistance.
• Knurled hex socket head provides improved grip and slip resistance during installation, even with gloves or in oily conditions.
• Fine 10-32 UNF thread delivers superior holding power and finer adjustment capabilities compared to coarse threads.
• Standard shoulder design with precise diameter and length tolerances for accurate component alignment and smooth rotational movement.
• Full regulatory compliance with ASME B18.3, RoHS 3, and REACH standards, ensuring material safety and international specification conformity.

Professional Applications & Engineering Value

This 316 Stainless Steel shoulder screw is engineered to address critical challenges in precision machinery and industrial assemblies. The corrosion-resistant material prevents degradation in humid, chemical, or marine environments, while the Class 3A thread fit and UNF fine thread provide exceptional clamping force and vibration resistance in dynamic applications. The knurled hex socket head ensures reliable torque transmission without stripping, and the precisely machined shoulder acts as a pivot, bearing surface, or locator in assemblies requiring exact component spacing. Ideal for robotics, conveyor systems, and precision instruments, this fastener maintains dimensional stability under 70,000 psi tensile loads, reducing maintenance frequency and downtime in demanding operations.

Specification Summary & Compliance

This shoulder screw features a 10-32 UNF fine thread with Class 3A fit for high-precision applications. The shoulder maintains tight tolerances (diameter: -0.004" to -0.002", length: -0.005" to 0.005") to ensure consistent alignment. Manufactured in compliance with ASME B18.3 specifications, it also meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, guaranteeing material safety and restricted substance compliance for global industrial use.
