Key Features & Benefits at a Glance
- Superior vibration resistance with an integrated internal-tooth lock washer that prevents loosening under dynamic loads, ensuring long-term joint integrity.
- Excellent corrosion protection from passivated 18-8 stainless steel construction, ideal for harsh or humid industrial environments.
- High tensile strength of 70,000 psi provides reliable clamping force and durability in demanding mechanical applications.
- Secure and efficient installation with a Phillips No. 2 drive and pan head design, allowing for easy torque application and reduced slippage.
- Wide compatibility due to UNC coarse threads and Class 2A fit, facilitating quick assembly and interchangeability in standard tapped holes.
- Full threading along the 3/8" length ensures maximum grip and engagement depth for enhanced holding power.
- Dual-material reliability with a 410 stainless steel lock washer, offering consistent performance and corrosion matching with the screw.
Professional Applications & Engineering Value
This 8-32 UNC coarse thread screw with an internal-tooth lock washer is engineered to address common industrial challenges such as vibration-induced fastener failure and corrosion. The 18-8 stainless steel material, combined with a passivated finish, resists oxidation and chemical exposure, making it suitable for outdoor equipment, automotive assemblies, and electronic enclosures. The pan head and Phillips drive enable straightforward installation in tight spaces, while the lock washer bites into mating surfaces to maintain clamp load. Ideal for machinery, conveyor systems, and panel fastening, this screw ensures operational safety and reduces maintenance needs in vibration-prone environments.
Specification Summary & Compliance
This screw adheres to Class 2A thread fit per UNC standards, ensuring precise dimensional accuracy. It meets ASME B18.13 specifications for screw and washer assemblies, and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free of hazardous substances. The fully threaded design and coarse pitch provide reliable engagement, backed by a tensile strength rating of 70,000 psi.
