- Reduced weight and space usage due to the thin hex profile, beneficial for compact assemblies.
- Consistent performance under stress with Grade 2 strength rating, suitable for general-purpose fastening.
- Broad compatibility with UNF fine threads (3/8"-24), offering excellent vibration resistance in machinery.
- Compliance with environmental regulations including RoHS 3 and REACH, ensuring safe use in regulated industries.
Professional Applications & Engineering Value
This 3/8"-24 UNF left hand thin hex nut is engineered to address specific industrial challenges where standard right-hand threads may fail. Made from black-oxide steel, it provides superior corrosion protection, extending service life in harsh conditions like automotive or machinery assemblies. The thin hex profile reduces weight and saves space, making it ideal for compact designs without compromising strength. With a Class 2B thread fit and left-hand thread direction, it ensures secure fastening in applications prone to reverse rotation, such as rotating shafts or specialized equipment. Compliant with ASTM A108, it guarantees material integrity, while its fine thread spacing enhances vibration resistance, minimizing maintenance needs in demanding environments.
Specification Summary & Compliance
This nut features a 3/8"-24 UNF fine thread with Class 2B thread fit for precise tolerance, adhering to ASTM A108 standards. Dimensions include a width of 9/16" and height of 7/32", with a Grade 2 strength rating for reliable performance. It is RoHS 3 (2015/863/EU) compliant with exemption 6(a) for lead in steel and REACH (EC 1907/2006) compliant as of 01/17/2023, ensuring environmental and safety regulations are met.
