What hardware is included in the GrovTec GTHM47 set?

The GTHM47 set includes one 7/8 inch threaded machine screw swivel stud with a knurled hex nut, one 3/4 inch wood or composite screw swivel stud, and two non-marring spacer washers. Both studs are machined from solid steel with a durable, corrosion-resistant black oxide finish to withstand tough Australian outback conditions.

Will these studs work directly with M-LOK or Picatinny modular rails on modern rifle stocks?

No, the GTHM47 swivel studs are designed specifically for traditional wooden, laminated, or dense composite stocks requiring direct screw-in or through-bolt installation. They are not compatible with modern modular rails like M-LOK, KeyMod, or Picatinny unless you use a dedicated stud-to-rail adapter.

How do I correctly install the machine screw versus the wood screw on my rifle stock?

The 3/4 inch wood screw is designed to thread directly into solid timber or dense polymer buttstocks. The 7/8 inch machine screw is intended for the fore-end of the stock, where it passes completely through a pre-drilled channel and secures underneath using the included knurled hex nut for maximum pull-through resistance under heavy loads like bipod mounting.

Are these swivel studs compatible with standard Harris-style bipods and sling swivels?

Yes, both studs feature standard cross-drilled heads designed to accept all standard QD quick-detach sling swivels, Uncle Mike’s style swivels, and stud-mounted bipods such as Harris-style units. The included non-marring spacer washers cushion the contact point against your stock finish to prevent scratching and ensure a snug fit.

Rifle Swivel Studs - GrovTec GTHM47

The GrovTec Swivel Studs Set (Model GTHM47) provides standard mounting attachment points on firearm stocks for quick-detach (QD) sling swivels and stud-mounted bipods. Precision-machined from solid steel with a corrosion-resistant black oxide finish, the set includes one 7/8" machine screw stud with a knurled hex nut, one 3/4" wood/composite screw stud, and two non-marring spacer washers. This hardware allows shooters to install secure anchor points across solid wood, laminated timber, and dense synthetic buttstocks and fore-ends.

Key Features

Fore-End Anchoring: Features a 7/8" threaded machine screw swivel stud paired with an internal knurled hex nut to maximize pull-through resistance inside the fore-end stock channel.
Buttstock Mounting: Includes a 3/4" wood screw swivel stud designed for direct threading into timber, polymer, or dense composite buttstocks.
Surface Protection: Supplied with two non-marring spacer washers that cushion the hardware against the stock finish to prevent surface damage and ensure a tight seat.
Broad Accessory Compatibility: Cross-drilled stud heads accept standard 1" and 1.25" quick-detach sling swivels, Uncle Mike's style loops, and Harris-style bipod clamps.
Durable Construction: Precision-machined steel hardware treated with a black oxide finish for baseline outdoor corrosion resistance.
