ARP Universal Bolt 3/8-16 Thread

These stainless steel bolts feature a 3/8-16 thread pitch and measure 1.250 inches in length. They are designed for universal automotive and garage applications requiring high-quality fasteners. The polished finish provides corrosion resistance suitable for various environments. Each set contains five pieces for multiple installation points.

12-Point Head Installation

The 12-point head design allows engagement from multiple angles using standard 3/8 inch drive tools. This can simplify access in tight engine bays or chassis areas where a conventional hex head might be difficult to reach. Ensure threads are clean and undamaged before installation to prevent cross-threading. Proper torque application is essential to maintain clamp load without stretching the fastener.

Sustained Load Behaviour

ARP fasteners are manufactured to withstand the high stresses found in racing environments since 1968. The stainless construction resists fatigue under repeated thermal cycles and vibration. Polished surfaces reduce stress risers that can initiate cracks during prolonged use. These bolts maintain clamping force in demanding driveline and engine applications over extended periods.
