Threaded Wood Inserts Kit — Reliable Metal Threads in Any Wood Surface
Stripped screw holes and weak wood joints are a constant frustration for furniture builders and DIYers. This 162-piece threaded insert kit gives woodworkers, cabinet makers, and home improvement enthusiasts a permanent solution — installing durable metal threads directly into wood for bolt connections that hold firm over years of use.
The kit includes carbon steel inserts with a smooth, burr-free yellow zinc plating finish, available in 8 size combinations across 4 popular thread diameters (1/4-20 and 5/16-18), with lengths ranging from 10mm to 25mm. A 3mm hex wrench is included for immediate installation without additional tools.
Typical applications include flat-pack furniture assembly, cabinet hinge reinforcement, workbench construction, and modular shelving systems — anywhere a removable, reusable bolt connection is needed in wood.
Key Features
- 🛠️ Complete 162-Piece Assortment Kit — Covers the most commonly needed insert sizes in a single purchase, eliminating the need to source individual sizes separately.
- ⚙️ 4 Popular Thread Sizes with Multiple Length Options — Includes 1/4-20 and 5/16-18 threads in 10mm, 15mm, 20mm, and 25mm lengths to match varying wood thickness requirements.
- 🛡️ Zinc-Plated Carbon Steel Construction — Yellow zinc plating provides corrosion resistance while the carbon steel core delivers the tensile strength needed for load-bearing furniture joints.
- 🔧 Includes Free 3mm Hex Wrench — Ready to install straight out of the box; no additional tools required for standard installations.
- ✋ Non-Slip Flange Design — The flanged head seats flush against the wood surface and prevents the insert from spinning or pulling through under load.
- 📦 Organized Storage Kit — Inserts are sorted by size for fast identification on the job, reducing setup time during assembly or repair work.
