Description
- Precision Fine-Thread Fit (5/16"-24 x 3"): Engineered with a 5/16-inch nominal diameter, 24 TPI (National Fine) pitch, and a full 3-inch under-head length.(Builder's Note: Fine-thread fasteners feature a larger minor diameter and shallower thread pitch than coarse threads, delivering superior tensile strength, finer torque adjustments, and maximum resistance to backing out under intense chassis vibration).
- Fully Threaded Tap Bolt Design: Machined with continuous threads running the entire 3-inch shaft right up to the underside of the hex head. Ideal for through-bolting applications, tapped blind holes, and custom fabrication brackets where maximum thread engagement or wide adjustment range is required.
- 18-8 / 304 (A2) Stainless Steel Construction: Forged from premium 18-8 (Grade 304 / A2) stainless steel with a clean, plain finish. Built to resist rust, corrosion, moisture, and harsh shop chemicals—making these cap screws reliable for both exposed outdoor environments and clean motorsport builds.
- Standard 1/2" Hex Drive Head: Features a precision-formed six-sided hex cap head (1/2" width across flats) for positive wrench or socket engagement, minimizing rounding during high-torque installation and fast between-round maintenance.
