Can I install these 3/4-inch wood screws into synthetic or polymer rifle stocks?

No, the GrovTec GTHM51 wood screws are designed specifically for solid timber or laminated wooden stocks requiring a minimum timber depth of at least 3/4 inch. If you are mounting hardware onto thin or hollow synthetic and polymer stocks, you will need a machine screw stud variant that uses a backing nut or washer rather than direct wood threads.

What is included in the GrovTec GTHM51 package, and are they suitable for workshop or multi-gun use?

The GTHM51 comes as a bulk 12-pack of steel sling swivel studs featuring a corrosion-resistant black-oxide finish and 0.75-inch screw threads. This bulk quantity makes it highly cost-effective for gunsmiths, workshops, and firearm owners maintaining or retrofitting multiple wooden stocks across their collection.

Are these swivel studs compatible with standard hunting slings and bipods used in the Australian bush?

Yes, these studs feature an industry-standard head profile with a cross-hole that accepts all standard quick-detach (QD) sling swivels, standard stud-mount rifle slings, and stud-mounted hunting bipods like Harris-style units. The steel construction and deep coarse wood threads provide reliable pull-out resistance during demanding multi-day carry and hunting trips in the outback.

Do I need any special firearm licenses or compliance certificates to purchase these swivel studs in Australia?

No special firearms licenses or regulatory permits are required to purchase the GrovTec GTHM51 in Australia. Because these are unpowered, passive mechanical hardware components rather than regulated primary firearm parts like receivers or barrels, they are freely available for retail purchase and shipping.

Swivel Studs - GrovTec GTHM51

Manufactured from steel with a black-oxide finish, each stud features coarse threads designed to thread securely into pre-drilled pilot holes in solid or laminated timber. The stud head is cross-drilled to standard dimensions, ensuring full compatibility with universal quick-detach (QD) sling swivels and Harris-style stud-mounted hunting bipods. Supplied in a bulk 12-pack, this hardware kit supports multiple firearm installations and maintenance jobs.

Who is the Grovtec ¾" Wood Screw - 12 Pack for?

Gunsmiths and firearm workshops maintaining multi-gun fleets — requires bulk inventory, supplied in a 12 studs per pack bundle to install standard wood screw sling swivel studs across multiple client rifles and workshop projects.
Hunters and shooters retrofitting wooden rifle stocks — requires a deep timber anchor point, utilizing a 0.75-inch thread length to mount standard sling swivels and bipods securely into wooden stocks.
