All-in-One Complete Installation Kit
This 5/16"-18 threaded insert set includes threaded inserts, matched twist drill bit and hex Allen wrench as a full installation combo. You won’t need to purchase separate drilling or driving tools to finish assembly jobs. All matching hardware eliminates extra part matching work and shortens your project preparation time.
Standard Precise 5/16"-18 Inner Thread Spec
Every insert adopts universal industry 5/16"-18 internal thread, compatible with all standard 5/16"-18 machine bolts on the market. Precision tapped inner threads enable smooth screwing in and out without cross-threading or thread stripping.
Heavy-Grip External Thread & Anti-Sink Flange Head
Full coarse outer threads deeply bite into base materials to deliver strong anti-loosening load-bearing force. Integrated circular flange prevents over-sinking and keeps the insert surface flush with workpieces. Internal hex socket perfectly matches the supplied Allen wrench for stable, uniform torque during installation. Even load distribution avoids splitting or cracking thin panels and soft substrates.
Zinc-Plated High-Strength Carbon Steel Material
These inserts are made of solid tensile carbon steel to withstand heavy loads and frequent use cycles. Color zinc electroplating provides reliable rust-proof, oxidation-resistant and wear-resistant performance. The rigid steel body resists bending and deformation even under long-term furniture and equipment stress. The bright plated finish stays neat in mildly humid garages, workshops and indoor living spaces.
Wide Multi-Material Compatibility
It fits all common wood types: hardwood, softwood, plywood, MDF, particle board, bamboo and timber. It works with non-wood porous substrates: composite board, PVC/ABS plastic sheet, resin blanks, craft foam, cork panels, plasterboard and cement fiber boards. The metal inner liner protects fragile base materials from fiber tearing caused by repeated bolt mounting.
Concise List of Application Scenarios Household Furniture
These 5/16"-18 threaded inserts are widely applied for assembling and repairing household furniture including tables, desks, chairs, bed frames, cabinets, floating shelves and outdoor patio benches, crafting handmade wood decor, display stands, resin art fixtures, jewelry racks and custom photography rigs, building workshop workbenches, tool chests, storage racks and woodworking jigs, installing retail display racks, café table frames, exhibition booth structures and hotel decorative fixtures, modifying RC models, drone landing gear and 3D printed composite parts, as well as reinforcing stripped threaded holes and load-bearing joints on wood, composite, PVC, resin, foam, cork and drywall substrates for all DIY, commercial and hobby maintenance projects.
Easy Beginner-Friendly Installation
Drill matching pre-holes on workpieces with the included twist drill bit for tight fit. Screw the insert evenly into pre-drilled holes with the hex wrench until the flange lies flat. Installed inserts support countless times of bolt disassembly without damaging surrounding materials. No professional equipment required; new DIY users can finish installation quickly.
