Locking Socket Jam Screw, Plain Alloy Hrc 45 53 (USA) (Inch)
Locking Socket Jam Screws, Plain Alloy (HRC 45–53) are high-strength fastening solutions designed to provide maximum holding power and resistance to loosening under vibration. Manufactured in the USA from heat-treated alloy steel, these jam screws achieve a hardness range of HRC 45–53, making them ideal for demanding mechanical and industrial applications. The internal hex socket allows for precise installation, while the locking feature helps maintain secure positioning once set.
Commonly used in power transmission assemblies, heavy machinery, tooling, and OEM equipment, locking socket jam screws are engineered for high torque and repeated load conditions. The plain finish is well-suited for controlled environments where additional coatings are unnecessary. Designed to lock in place against mating threads, these screws reduce the risk of backing out due to shock, vibration, or thermal cycling, ensuring long-term reliability in critical applications.
