Gibraltar 41055G Unequal Double Threaded Stud 7/8-9 8 in

Product Description

The GIBRALTAR 41055G is an unequal double threaded stud with a 7/8-9 thread size and an overall length of 8 inches. It is manufactured from carbon steel with a black oxide finish and carries a material grade of 5. The long thread measures 2.5 inches and the short thread measures 1.25 inches, making the two ends unequal in engagement length. This type of stud is used to create a permanent or semi-permanent fastening point in one component while allowing a nut to be threaded onto the exposed end. It is typically installed by millwrights, maintenance mechanics, or industrial tradespeople working on structural assemblies, machinery, or equipment mounting applications.

This stud is suited for industrial and commercial applications where a threaded fastener must be anchored into a tapped hole on one end and accept a mating nut or coupling on the other. The unequal thread length configuration allows the shorter end to seat into a fixed component while the longer end provides additional thread engagement for the external fastener. Applications include machinery bases, equipment frames, flanged connections, and general structural fastening where carbon steel strength and black oxide corrosion resistance are appropriate for the service environment.

Key Features

• 7/8-9 thread size with Thread Fit Class 5 for controlled engagement tolerance
• 8 inch overall length accommodates thicker assemblies or extended projection requirements
• Unequal thread lengths: 2.5 inch long end and 1.25 inch short end for differentiated seating and clamping
• Carbon steel construction with material grade 5 provides solid tensile and shear strength
• Black oxide finish offers mild corrosion resistance and reduces light reflection in service environments
• No flat ground on shank, maintaining full round cross-section along the body

Compatibility

Designed as a standard unequal double threaded stud for use in tapped holes or couplings requiring 7/8-9 thread form in carbon steel industrial and commercial fastening applications.

Installation Notes

Installation is typically performed by millwrights or maintenance mechanics using a stud driver or double-nut method to thread the short end into a pre-tapped hole. Ensure the receiving hole is clean, properly tapped to the correct thread class, and free of debris before installation. Torque should be applied only to the short end during seating to avoid damaging the exposed long thread. Follow applicable facility maintenance standards and equipment manufacturer guidelines for fastener preload requirements.
