Key Features & Benefits at a Glance
- Superior corrosion resistance with passivated 18-8 stainless steel construction, ideal for harsh industrial environments
- Enhanced load distribution through the wide truss head design, reducing surface damage and improving joint integrity
- High tensile strength of 70,000 psi ensures reliable performance under demanding mechanical stresses
- Precise Class 2A thread fit guarantees smooth installation and secure fastening in UNF fine-thread applications
- Excellent drive engagement with Phillips No. 2 drive, minimizing cam-out and speeding up assembly processes
- Full threading along the 2" length provides maximum grip and adjustability in deep or variable material thicknesses
- Consistent hardness (Rockwell B70) maintains dimensional stability and resists wear over repeated use
Professional Applications & Engineering Value
Engineered for demanding industrial settings, these 10-32 UNF fully threaded screws address common challenges like vibration loosening and corrosion-induced failure. The passivated 18-8 stainless steel offers exceptional resistance to moisture and chemicals, extending service life in applications from machinery assembly to outdoor enclosures. The rounded truss head distributes clamping force over a wider area, preventing surface marring on sensitive materials while the fine thread spacing ensures tighter seals in precision equipment. With a Phillips No. 2 drive, installation is efficient and reliable, reducing tool slippage in high-volume production lines. These screws are ideal for securing components in electronics, automotive, and aerospace industries where corrosion-resistant fasteners with consistent performance are critical.
Specification Summary & Compliance
This screw features a 10-32 UNF thread with Class 2A tolerance for precise fit, fully threaded along a 2" length. It complies with ASME B18.6.3 manufacturing standards, ensuring dimensional accuracy and reliability. The product is RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, meeting environmental and safety regulations for global industrial use.
