Description
GrovTec built these studs to solve one of the most common projects that lands on a gunsmith's bench: adding a solid sling anchor to a wood-stocked rifle or shotgun. Each stud threads directly into the wood with standard sling-swivel screw threads, giving you a place to hook a swivel for a carry sling or clamp on a bipod. You get twelve of them per pack in a black finish, so you are set for several builds instead of chasing down parts one at a time.
Where the GTHM51 Studs Fit
These are the 3/4-inch wood screw version, which is the go-to length for the rear stud on most factory and aftermarket wood stocks. The threads match the industry-standard swivel stud pattern, so they pair up with GrovTec's own swivels along with sets from Uncle Mike's and other common brands. That compatibility matters when you already have a favorite sling or a quick-detach swivel you want to keep using.
Installing the GrovTec Wood Screw Studs
Mounting one is a straightforward drill-and-thread job. Most folks mark the spot on the toe of the buttstock, drill a pilot hole in the neighborhood of 5/32 inch, then run the stud in using a pin punch through the loop as a makeshift wrench. A dab of epoxy in the hole is cheap insurance on wood, since the fibers can compress and loosen over time. Take it slow on the final turns so you do not strip the threads or crack the finish, and stop when the base sits flush.
What the 12-Pack Gets You
Buying a dozen makes sense if you tinker with more than one rifle or run a small shop. You will have extras for the inevitable dropped stud, a project stock down the road, or a buddy's deer rifle that showed up without a sling point. GrovTec makes these in the U.S.A., and they are a proven, no-drama part that does exactly what it should once it is seated in the wood.

Frequently Asked Questions
Will these GrovTec swivel studs work with my existing sling swivels?
Yes. The GTHM51 studs use the standard sling-swivel thread pattern, so they accept GrovTec swivels along with quick-detach and fixed swivels from other common brands. If your current sling hooks onto a typical stud, it will hook onto these.
What length screw is the GTHM51 and where does it go on the stock?
These are 3/4-inch wood screw studs, which is the usual length for the rear sling point on the toe of a buttstock. GrovTec makes shorter and longer versions for other spots, but the 3/4-inch is the most-used size for wood stocks. The 12-pack gives you plenty for multiple guns.
How do I install a wood screw swivel stud without messing up the stock?
Mark your spot, drill a pilot hole around 5/32 inch, then thread the stud in using a pin punch through the loop as a lever. Going with a proper pilot hole and adding a little epoxy keeps the threads from stripping or working loose in the wood over time. Snug it down flush and stop before you overtighten.
Are these studs only for wooden stocks?
Correct. The GTHM51 has wood screw threads, so it is meant for wood stocks specifically. For synthetic or laminate stocks with a molded insert you would want the machine screw style stud instead, which GrovTec also offers.
