Challis Hex Drive Bushings – Stainless Steel – Standard Grip (4-Pack)

Challis Hex Drive Bushings make installing and removing full-size 1911 grips fast, precise, and hassle-free. The stainless hex head delivers maximum strength and holds torque securely under repeated use. Additionally, optional O-rings improve grip stability and protect your frame finish. Together, these features ensure your 1911 grips stay solid, secure, and consistent.

Fast and Simple Installation

First, slide a bushing into a 7/32″ nut driver. Then, turn it into place. The socket keeps the bushing straight, so threads engage cleanly. Consequently, you never need to start the bushing by hand or switch tools mid-job. Installation becomes quicker, smoother, and more accurate. Even beginners can achieve professional results.

Strong Hex Head Design

Next, the hex head drives the bushing firmly. It resists deformation and prevents burrs from forming on the top. Unlike slotted bushings, it maintains strength, precision, and clean installation every time. Because of this design, you can apply the proper torque without worrying about damaging the bushing. This is especially valuable for heavy-duty grips and repeated assembly and disassembly.

Stable and Secure Grip

Apply the recommended torque—27 in-lbs for steel frames and 20 in-lbs for aluminum frames—and the bushing holds steady under firing stress. In addition, heavy grips like G10, aluminum, or other dense materials remain firmly in place. As a result, the gun feels solid in your hand, and the grip does not shift during recoil. Full-size grips work perfectly without modification.

Optional O-Rings for Maximum Performance

While O-rings are not required, we highly recommend them. They provide extra security by keeping grip screws tight and preventing the frame from scuffing. Furthermore, O-rings deliver a consistent feel and a more secure mounting, enhancing both performance and comfort. When used together with the hex head, O-rings create the most reliable grip fit available for your 1911.

Easy Removal and Reuse

When it’s time to remove the bushing, simply use a 7/32″ nut driver or socket. No special tools, easy-outs, or forceful prying are needed. Moreover, you can remove the bushings for refinishing or upgrades without damaging them. This reusability saves time, effort, and money, while preserving your original hardware.
