The GrovTec One ¾" Wood Screw Swivel Stud with Spacers (Model: GTHM48) is a precision-machined carbon steel mounting base designed to anchor into solid hardwood, softwood, or dense laminate firearm stocks. Featuring a ¾-inch (~19.05 mm) coarse wood thread, it creates a robust anchor point on wooden buttstocks and forends for standard quick-detach (QD) sling swivels, 1-inch to 1.25-inch sling loops, and Harris-style stud-mounted bipods. The package includes protective spacer washers that sit between the timber stock and the stud base to prevent finish damage during installation.

Key Features

• Precision Carbon Steel Construction: Machined from solid carbon steel with a protective blued/black oxide finish for long-term wear resistance.
• Direct Timber Threading: Engineered with deep, coarse wood screw threads designed specifically for dense timber and laminate stocks.
• Protective Spacers Included: Features dedicated spacer washers that prevent stock gouging and finish compression when torquing the stud into place.
• Standard Accessory Interface: Standard cross-hole and pivot profile accepts standard American and European QD sling swivels and stud-mounted bipods.

Who is the GrovTec One ¾" Wood Screw Swivel Stud for?

• Hunters and sport shooters with wooden centrefire or rimfire rifles — installs securely into timber buttstocks requiring a ¾-inch thread engagement depth to support standard rifle slings and bipods after preparing a 5/32-inch pilot hole.
• Owners of classic wooden shotguns needing replacement hardware — replaces stripped or missing sling attachment points by seating into solid wood buttstocks using a 7/32-inch countersink and protective spacer washer to preserve the stock finish.

Less suitable for: Thin-walled forends with less than ¾-inch timber depth or hollow synthetic stocks (which require shorter ½-inch wood screws or machine screw studs with internal backing nuts), as well as modern aluminum or polymer M-LOK and KeyMod handguards (which require dedicated rail-to-stud adaptors).
