The Grex P6 23-Gauge Galvanized Pin Nail Multi Pack, 3/8" to 1-3/8", 3000 Pack is a 23-gauge headless pin assortment built for fine finish fastening with Grex P6 series pinners. This is a 23-gauge headless pin nail assortment designed for trim work, cabinetry, molding, and other detailed fastening jobs where you want a clean look with minimal hole size. Model Number: P6/MP-3. For anyone setting up a pin nailer, this pack gives you the most-used lengths in one box so you can test, fit, and work without guessing which single size to order first.

What makes this pack useful is the spread of sizes. You get 500 pins each in 3/8 inch, 1/2 inch, 5/8 inch, 3/4 inch, 1 inch, and 1-3/8 inch lengths, for a total of 3,000 pins. That range covers a lot of real shop and jobsite situations. Shorter pins help with light hold and tiny parts where blow-through is a risk. Mid-length pins are the everyday choice for trim and detail work. The longer sizes give you more bite when you need better hold in thicker material or layered assemblies.

These are headless pins, which is the whole point if you are doing work where appearance matters. In trim, small moldings, edge details, veneers, and light tack fastening, a headless pin keeps the hole nearly invisible and reduces cleanup before finish work. That is why 23-gauge pins are a go-to for cabinet shops, furniture work, and punch-list trim jobs. They are not meant to replace a brad nail when you need heavy holding power. They are meant to hold parts in place cleanly while glue sets or to fasten delicate material without splitting it up.

Grex also puts real emphasis on fastener quality here. The source data calls out precision wire drawing for consistent pin dimensions, adjusted carbon content by pin length for proper tensile strength, and durable yet flexible collation to reduce strip breakage. In plain terms, that means the pins are made to feed consistently and hold up better in the magazine. On a pin nailer, that matters. Tiny fasteners do not leave much room for sloppy manufacturing, and poor collation can turn a simple detail job into a jam-clearing session.

This multi pack is specifically useful for first-time owners of Grex pinners and for hobbyists who do not yet know which pin length they will reach for most. Instead of committing to a full box of one size, you get a working assortment that lets you dial in the right length by material thickness and task. It is also a smart refill option for pros who want common short and medium lengths on hand for punch work, install adjustments, or bench work in the shop.

Compatibility is straightforward. This pin nail multi pack is made for Grex P630, P635, P645, P645L, P650, and P650L pinners. If that is your platform, the pack makes sense as a starter assortment and everyday backup. If you do detailed woodworking, interior trim, cabinet installation, or small-part assembly, this is the kind of fastener pack that saves time because you are less likely to stop work and hunt for the one length you do not have.
