Select Screw Length:
This is a 4-40 threaded fillister head screw with brass ferrule and brass press-fit nut. Both the ferrule and nut have straight knurls that pull into wood or plastic grips and keep the brass fitting from turning.

The brass parts press-fit into a 0.25 inch hole with a smaller hole (about 0.108 inch) for the number 4 screw.

This kit is used for most grips other than the very small or thin pocket pistols. It has ample surface area under the brass ferrule and nut to support any reasonable mounting or clamping force exerted on the grips by the screw. The high strength modern steel screw handles far more recoil and shearing force than larger, soft iron or screw-stock steel screws originally found in older guns.

The hardware kit is sold as a set with one ferrule, one nut, and one screw. I also have separate screws without the brass parts. If you've ever tried to buy the straight-knurled, factory-original style ferrules and nuts, you'll appreciate the ability to get just one or two of these kits! Usually you have to either contract for 5,000 to 10,000 of them to get any at all, or settle for something that is not the right size and style or length. The screw will normally be cut to exact length by you for your gun. You can use an electrician's multi-purpose wire stripper/pliers with the machine screw cutting holes (a hole in one side of the pliers is threaded, and its matching hole opposite is not) for best results.

If you purchase a grip, I can include the screw without any additional shipping cost.

If you tell me the length of screw that you need, in the note section, I will be glad to select the nearest longer one available from inventory so you have less or perhaps no adjustment to make. The screws are available in 1-1/2 inch, 1-1/4 inch, 1-1/8 inch, 1 inch, 7/8-inch, 3/4-inch, and 5/8 inch lengths. Sometimes I have a few odd lengths in stock between these sizes. Normally if you don't specify I send you the one that fits the most guns, which is the 1-1/8 inch length.

A large number of standard size revolvers use 1-1/8 inch screw length, and smaller frame revolvers with small, fairly thin grips often use the 7/8-inch length. When in doubt get a longer screw than you think you need, because the grips may not be the same thickness as the ones which came with the gun.
