S-93996A607 6-32 Shoulder Screws

Key Features & Benefits at a Glance

• Vibration-resistant locking: Permanent nylon patch thread locker prevents loosening under dynamic loads, ensuring reliable performance in high-vibration environments.
• Corrosion-resistant durability: Made from 18-8 stainless steel, offering excellent resistance to rust and corrosion for long service life in harsh conditions.
• High-strength construction: With a tensile strength of 70,000 psi and Rockwell B55 hardness, this screw handles heavy-duty mechanical stresses without failure.
• Precise alignment and spacing: The smooth, standard socket head and precise shoulder fit (5/32" diameter, 5/16" length) enable accurate component positioning and reduced assembly errors.
• Wide temperature tolerance: Nylon patch operates effectively from -70° to 250°F, making it suitable for applications exposed to extreme thermal cycles.
• Easy installation and removal: Hex drive (3/32") allows for secure tool engagement and efficient maintenance, while UNC coarse threads facilitate quick assembly.
• Regulatory compliance assurance: Meets RoHS 3 and REACH standards, ensuring safety and environmental responsibility for global industrial supply chains.

Professional Applications & Engineering Value

This 6-32 UNC shoulder screw is engineered to address common industrial challenges such as component misalignment and vibration-induced fastener failure. The 18-8 stainless steel material provides inherent corrosion resistance, ideal for machinery in humid or chemically aggressive settings like automotive assemblies or food processing equipment. The nylon patch thread locker offers a permanent locking solution that maintains integrity across a broad temperature range (-70° to 250°F), eliminating the need for additional adhesives in vibration-resistant applications. Combined with a Class 2A thread fit and precise shoulder dimensions, it ensures secure mounting of rotating parts, bearings, or linkages, reducing maintenance downtime and enhancing operational reliability in precision engineering projects.

Specification Summary & Compliance

This shoulder screw adheres to UNC coarse thread standards with a Class 2A thread fit for consistent dimensional accuracy. Key specifications include a 6-32 thread size, 3/16" thread length, and shoulder diameter of 5/32" with tight tolerances. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for industrial use globally.
