Metallics M50100 Anchors .300" Head Drive Pins W/ 7/8" (Jar 100)

The M50100 drive pins have a .300 inch head and a 7/8 inch pin length. They ship as a jar of 100 pins under manufacturer part number M50100.

Drive pins like the Metallics M50100 are powder or hammer driven fasteners for anchoring into concrete and masonry, and they are stocked as electrical fasteners and anchors for attaching straps, clips, boxes and brackets to hard substrates. The .300 inch head gives bearing area against the item being fastened, and the 7/8 inch pin sets the embedment depth you get into the concrete.

A 7/8 inch pin has to split its length between the thickness of what you are fastening and the embedment in the concrete, so it suits thin items such as a steel strap, clip or box ear. If you are shooting through furring, wood blocking or a thicker bracket, step up to a longer pin so you keep adequate embedment behind the fastened item.

They come in a jar, 100 pins per jar. The jar pack keeps the pins contained in a pouch or gang box between shots, which is how electricians typically buy them for repeat conduit strap and box fastening work.
