Driveline Socket Capscrew 7/16" - 20 X 1"

Driveline Socket Capscrew 7/16" - 20 X 1"

This 7/16"-20 x 1" driveline socket capscrew is a high-strength fastener designed to secure critical driveline components, including U-joints, yokes, and companion flanges, to the PTO or gearbox in concrete mixer trucks. Featuring a fine UNF thread pitch and an internal hex socket head, it allows for high-torque tightening in tight clearances where standard hex bolts cannot fit. Replacing worn, stretched, or damaged driveline bolts is essential during U-joint maintenance or driveshaft replacement to prevent driveline separation and ensure safe power transmission. It is compatible with standard 1310 and 1350 series driveline assemblies found in heavy-duty concrete equipment.

Key Features

• 7/16"-20 fine thread (UNF) provides superior grip and vibration resistance in high-torque applications
• 1-inch under-head length designed for standard driveline yoke and flange mounting
• Socket head design allows for high-torque installation in tight driveline clearances where standard wrenches cannot fit
• High-tensile steel construction withstands heavy rotational loads from the PTO to the mixer gearbox
