Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh industrial environments and outdoor applications.
- Enhanced vibration resistance thanks to the serrated locking flange, which prevents loosening under dynamic loads.
- High tensile strength of 100,000 psi ensures reliable performance in demanding mechanical assemblies.
- Easy installation and removal with an external hex drive and coarse UNC threads, reducing assembly time.
- Consistent thread quality with Class 2A fit, providing secure fastening and interchangeability.
- Full threading along the 1-1/4" length offers maximum grip and load distribution across the entire shank.
- Compliance with RoHS 3 and REACH standards guarantees environmental safety and regulatory acceptance.
Professional Applications & Engineering Value
This 12-24 UNC hex head screw is engineered to address common industrial challenges such as vibration-induced loosening and corrosion. The 18-8 Stainless Steel material provides excellent resistance to rust and chemical exposure, making it suitable for outdoor equipment, marine applications, and food processing machinery. The serrated flange acts as an integrated washer, biting into surfaces to maintain clamp load under stress. Combined with a coarse thread design, it ensures quick assembly and disassembly, reducing labor costs in high-volume manufacturing and maintenance operations. Its fully threaded body enhances holding power, while the external hex drive allows for high-torque installation with standard tools.
Specification Summary & Compliance
This screw adheres to UNC coarse thread standards with a Class 2A thread fit for consistent dimensional accuracy. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances. Manufacturing follows industry norms for inch-system fasteners, with precise thread diameter (0.216") and length (1-1/4") tolerances. The Rockwell B100 hardness and 100,000 psi tensile strength confirm its reliability in structural and mechanical applications.
