1/2 Stud - 2.750 Long Broached

The ARP 1/2 Stud - 2.750 Long Broached (AR2.750-1LB) is a precision fastening component engineered for high-performance engine assembly and critical mechanical applications. This broached stud delivers the dimensional consistency and material strength required in situations where standard fasteners cannot provide adequate reliability under load. The 2.75-inch length and 1/2-inch diameter make it suitable for mounting, support, and alignment tasks in automotive, machinery, and industrial rebuild scenarios where exact fit and durability are non-negotiable.

Manufactured from chromoly steel with black oxide finish, this ARP broached stud resists corrosion while maintaining the hardness and fatigue resistance that chromoly is known for in demanding environments. The broached design—where the internal geometry is precisely cut rather than rolled—ensures consistent material flow and eliminates weak points that can develop under cyclic loading. This stud accommodates both 1/2-13 and 1/2-20 thread specifications, providing flexibility for different assembly configurations. At just 0.13 lbs, the fastener remains lightweight while maintaining the strength necessary for applications requiring precision fit and pull-through reliability.

This ARP stud is intended for engine builders, restoration specialists, and mechanical engineers who require verified component quality for high-stress assemblies. Whether used in block preparation, head fastening, or structural support roles, the broached construction delivers consistent clamping geometry and eliminates the variability introduced by standard fastener manufacturing. The black oxide coating provides additional corrosion protection, extending service life in shop and field environments.

ARP's reputation in fastening solutions reflects decades of experience supporting precision assembly across racing, military, and industrial sectors. Each broached stud is produced to exact specifications, ensuring that critical fastening applications receive components designed to outlast inferior alternatives and maintain performance across thousands of operating cycles.
