Secure your high-stress assemblies with the ultra-reliable 1/4-20 x 4" Socket Head Cap Screw. Manufactured from high-tensile heat-treated alloy steel, this internal-wrenching fastener provides significantly greater tensile strength than standard Grade 5 or Grade 8 hex head bolts. Its sleek cylindrical head features a knurled outer circumference for a firm grip during manual adjustment and a precision-broached hexagonal drive to handle high torque specifications without slipping.
- Maximum Tensile Strength: Built from premium alloy steel designed for heavy-duty industrial machinery, fixtures, automotive setups, and close-tolerance precision assemblies.
- Black Oxide Treatment: Finished with a thermal black oxide coating that minimizes light reflection and adds mild corrosion protection for oiled indoor applications.
- Full Thread Configuration: Fully threaded down the entire 4-inch shank length, giving you maximum gripping surface area and flexible engagement depth in tapped holes.
- Space-Saving Design: Internal hex drive geometry requires no clearance for external wrenches, allowing counterbored installations directly flush into tight spaces or pockets.
- Unified Coarse Thread: Features standard 1/4" diameter with 20 threads per inch (UNC) to match universal imperial tapped blocks and nuts perfectly.
