The Grex P6 23-Gauge Pin Nail Multi Pack, 1-3/16" to 2", 2500 Pack is an assortment of galvanized headless pins made for Grex P6 series pinners and other compatible 23-gauge headless pin nailers. This is a 23-gauge headless pin nail assortment designed for fine fastening, trim detail work, and light assembly. Model number P6/MP-L. If you need a practical way to cover several common pin lengths without buying full boxes of each, this pack does the job.

What makes this pack useful is the spread of sizes. You get 500 pins each in 1-3/16 inch, 1-3/8 inch, 1-1/2 inch, 1-3/4 inch, and 2 inch lengths, for a total of 2,500 pins. That gives you flexibility when you are working across different materials and trim profiles. Shorter pins are useful when you want holding power without blowing through delicate stock, while the longer lengths give you a little more bite for thicker moldings and assembly work.

Grex also puts real attention into the fastener itself, not just the count in the box. The source data calls out precision wire drawing for consistent dimensions, carbon content adjusted by pin length for proper tensile strength, and durable but flexible collation to reduce strip fragmentation. On the bench or on site, that matters because consistent pins are less likely to create feeding issues and more likely to drive the way your pinner is supposed to.

Since these are headless 23-gauge pins, they are built for the kind of fastening where you want minimal surface disruption. That makes them a good fit for fine trim, furniture touch-up, small moldings, light decorative pieces, and detail work where a larger fastener would leave more cleanup behind. They are galvanized, which adds a little protection compared to plain steel fasteners for general shop and jobsite use.

Compatibility is straightforward and important here. This multi pack is listed as fitting Grex P630, P635, P645, P645L, P650, and P650L tools, and the packaging notes that it fits most 23-gauge headless pinners. If you are already in the Grex P6 platform, this is an easy buy because it is built around that series. If you use another 23-gauge headless pinner, verify your tool's fastener requirements before ordering.

This assortment makes the most sense for woodworkers, finish carpenters, cabinet installers, hobbyists, and first-time pin nailer owners who are still figuring out which lengths they reach for most. It is also a smart restock option for a shop that wants common lengths on hand without tying up shelf space in several larger packs. Bottom line: this is a practical fastener assortment, not filler. It lets your 23-gauge pin nailer cover more jobs with one package.
