Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh industrial environments and outdoor applications.
- High tensile strength of 70,000 psi ensures reliable performance under heavy loads and vibration, reducing the risk of fastener failure.
- Precise Class 3A thread fit provides tighter tolerances for secure mating with nuts and tapped holes, minimizing backlash.
- Robust Rockwell B70 hardness offers excellent durability and wear resistance, extending the screw's service life.
- Partially threaded design with 2 1/2" minimum thread length allows for optimal clamping force on specific joint sections.
- 3/4" hex drive socket head enables high-torque installation with standard tools, preventing cam-out and head stripping.
- Compliance with ASME B18.3, RoHS 3, and REACH guarantees consistent quality and material safety for regulated industries.
Professional Applications & Engineering Value
This 1"-8 UNC Socket Head Cap Screw in 18-8 Stainless Steel is engineered to address critical challenges in heavy machinery, automotive assembly, and structural frameworks. Its coarse thread design facilitates quick assembly and disassembly, even in dirty or debris-prone environments, while the Class 3A thread fit ensures vibration resistance and joint integrity. The partially threaded shank concentrates clamping force precisely where needed, preventing stress concentration on the threaded portion. With a 70,000 psi tensile strength and corrosion-resistant material, it solves durability issues in high-stress, corrosive applications, reducing maintenance downtime and replacement costs.
Specification Summary & Compliance
This screw features a 1"-8 UNC coarse thread with a Class 3A fit for precise dimensional accuracy, manufactured in compliance with ASME B18.3 standards. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental and safety compliance. The partially threaded design includes a minimum thread length of 2 1/2", with overall dimensions of 5" length, 1 1/2" head diameter, and 1" head height.
