Key Features & Benefits at a Glance
- Exceptional corrosion resistance in harsh environments thanks to 316 stainless steel construction, ideal for chemical, marine, and high-humidity applications.
- High tensile strength of 75,000 psi and Rockwell B96 hardness ensure reliable performance under heavy loads and prevent fastener failure.
- Coarse UNC thread design enables faster installation and reduced risk of cross-threading, saving valuable assembly time.
- Partially threaded shank with a 2-inch grip length provides superior clamping force and prevents loosening in vibrating machinery.
- Class 2A thread fit guarantees consistent, free-spinning assembly with standard nuts, streamlining the production process.
- External hex drive and standard hex head allow for high-torque application with common tools, ensuring a secure and tight fit.
- Compliance with ASTM A193 Grade B8M specification assures material quality and performance for high-pressure and high-temperature service.
Professional Applications & Engineering Value
Engineered for demanding industrial settings, these Grade B8M 316 stainless steel hex head screws deliver critical corrosion resistance where exposure to chemicals, saltwater, or extreme temperatures is a concern. The coarse UNC thread and partially threaded design provide excellent vibration resistance and clamping force, making them ideal for heavy machinery, pressure vessels, and structural assemblies. With a 75,000 psi tensile strength and Rockwell B96 hardness, they maintain integrity under stress, reducing maintenance needs and downtime. The external hex drive facilitates efficient installation, ensuring reliable performance in ASTM A193 compliant applications.
Specification Summary & Compliance
This 3/8"-16 UNC hex head screw features a Class 2A thread fit for standard assembly tolerance, with a coarse thread spacing, 3-inch length, and 2-inch grip length. Manufactured from 316 stainless steel to ASTM A193 Grade B8M specifications, it meets requirements for high-strength, corrosion-resistant fasteners. Complies with industry standards for material quality and is suitable for applications demanding RoHS and REACH environmental directives.
