Value Collection CD560522 Threaded Stud 7/16-14 Grade 8

Product Description

The VALUE COLLECTION CD560522 is an unequal lengths threaded stud machined from Grade 8 alloy steel with a zinc yellow dichromate finish. At 2.5 inches overall length, it features a 1.25-inch long-end thread and a 0.75-inch short-end thread, both cut to 7/16-14 UNC, with a 0.5-inch unthreaded shank between them. The zinc yellow dichromate coating provides corrosion resistance in moderate service environments. This type of fastener is installed by machinists, millwrights, maintenance technicians, and mechanical contractors in industrial and trade applications where a fixed double-ended threaded connection is required.

Unequal lengths threaded studs are used in equipment assembly, pump and motor mounting, structural clamping, and general mechanical fabrication where one end threads permanently into a tapped hole and the other end accepts a nut for clamping. The Grade 8 material rating makes this stud appropriate for higher-load fastening applications found in industrial machinery, HVAC equipment frames, and mechanical systems requiring reliable thread engagement under vibration or cyclic loading.

Key Features

• Grade 8 alloy steel construction for high tensile strength in demanding fastening applications
• Unequal thread lengths: 1.25-inch long end and 0.75-inch short end, both 7/16-14 UNC
• 0.5-inch unthreaded shank between threaded ends for precise positional registration
• Zinc yellow dichromate finish provides corrosion and oxidation resistance
• No flat ground on shank, keeping the profile clean for close-clearance installations
• 2.5-inch overall length suits a wide range of standard tapped-hole and clamping stack heights

Compatibility

Designed as a direct-fit replacement or standard-stock fastener for any application requiring a 7/16-14 UNC unequal lengths threaded stud at 2.5 inches overall length in Grade 8 alloy steel.

Installation Notes

Installation is performed by threading the short end fully into a pre-tapped hole using a stud driver or double-nut method, then securing the assembly with a nut on the long end. Power down or de-energize any associated equipment before fastener service on live mechanical systems. Follow applicable torque specifications for 7/16-14 Grade 8 hardware from the equipment manufacturer or relevant mechanical code. Avoid impact-driving the stud, as this can damage thread engagement and reduce clamp load integrity.
