Challis Hex Drive Bushings – Blue – Standard Grip (4-Pack)
The Challis Hex Drive Bushings – Blue – Standard Grip provide a fast, precise, and highly secure way to install and remove full-size 1911 grip bushings. By combining a strong hex-drive head with durable stainless construction and a clean blue finish, these bushings deliver long-term reliability while simplifying both installation and maintenance.
Fast, Simple, and Controlled Installation
Installing grip bushings should never feel risky or frustrating. With these Challis Hex Drive Bushings, the process stays quick and predictable from start to finish. Simply place the bushing into a 7/32″ nut driver and turn it into the frame.
Because the socket captures the hex head fully, the bushing stays perfectly aligned as the threads engage. As a result, you start straight every time. Moreover, you never need to start threads by hand or change tools mid-job, which saves time and reduces the chance of cross-threading.
Strong Hex Drive Design for Clean Results
Unlike traditional slotted bushings, the hex head applies torque evenly across the drive surface. Therefore, it resists burrs, slot damage, and top deformation during both installation and removal.
Because the hex drive stays fully engaged, you can apply proper torque with confidence. Consequently, the bushing seats cleanly and securely in the frame while maintaining a professional, damage-free appearance.
Secure and Stable Grip Mounting
Once installed, these bushings stay put under recoil. Apply the recommended torque—27 in-lbs for steel frames and 20 in-lbs for aluminum frames—and the bushing remains stable through repeated firing.
This stability becomes especially important when running heavier grip materials such as G10, aluminum, or other dense panels. As a result, your grips stay tight, consistent, and free from unwanted movement.
Optional O-Rings for Maximum Security
Although the bushings install perfectly without O-rings, adding them takes performance one step further. O-rings help keep grip screws tight, prevent scuffed frames, and absorb vibration during firing.
Because of this added cushioning and tension, grip panels feel more solid and secure. Most importantly, you gain the most stable grip mounting possible for hard-use pistols.
Easy Removal and Long-Term Reuse
When it comes time for refinishing or upgrades, removal stays just as easy as installation. Use the same 7/32″ nut driver or socket to back the bushing out cleanly.
Since the hex head resists damage, you avoid stripped slots, broken bushings, and frame scars. As a result, you can reinstall the same bushings after refinishing, saving money while preserving high-quality hardware.
