Material & Finish: Low-carbon steel (Grade 2/A307 equivalent) with zinc plating for corrosion resistance; tensile strength ~55,000–60,000 PSI. Alternatives like stainless 18-8 available for harsher conditions.
Thread Specs: 3/8"-16 UNC (coarse thread, 16 threads per inch); fully threaded from under the head to tip for maximum grip in tapped holes.
Head Design: Hexagonal head (9/16" across flats) with integrated washer face for even load distribution; external hex drive for high-torque installation (up to 50 ft-lbs.).
Dimensions: Diameter: 3/8"; length: 1" (assumed from label; body length under head); thread length: full 1".
Strength & Load: Proof load ~8,500 lbs.; suitable for medium-duty applications (e.g., not structural/high-vibration without Grade 5+). Shear strength ~10,000 PSI.
Installation: Tighten into pre-tapped 3/8"-16 hole or pair with hex nut; no self-tapping—drill and tap first. Use with jam nuts for adjustable setups.
