Professional Applications & Engineering Value

This 10-32 UNF Rounded Head Flanged Screw is engineered to address common industrial challenges such as corrosion, vibration loosening, and assembly inefficiency. The 18-8 Stainless Steel material provides excellent resistance to rust and chemical exposure, making it suitable for outdoor equipment, marine hardware, and food processing machinery. The fine UNF thread and Class 2A fit ensure tight, reliable connections in precision assemblies, reducing maintenance needs. The built-in flange acts as a built-in washer, increasing bearing surface and preventing pull-through in softer materials. With a right-hand thread direction and fully threaded design, it delivers consistent clamping force and is ideal for electronic enclosures, automotive components, and machinery where space is limited and durability is critical.

Specification Summary & Compliance

This screw adheres to UNF thread standards with a Class 2A thread fit for consistent dimensional accuracy and interchangeability. Manufacturing complies with industry norms for fine threading and right-hand direction. The product is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting stringent environmental and safety regulations for hazardous substances.
