High-Stability Industrial 4-Prong Tee Nut Set (QTN1112)
Rock-Solid Threaded Anchors for Heavy Woodwork
The POWERTEC QTN1112 is a professional-grade 50-pack of 3/8"-16 x 5/16" 4-pronged tee nuts, specifically precision-engineered to provide a permanent, non-rotating machine thread in any wood or plastic surface. These T-nuts are the definitive choice for woodworkers building heavy workbenches, jig assemblies, or rock climbing walls where a traditional wood screw would fail under high tension. Featuring a specialized 4-prong mechanical lock, these fasteners bite deep into the material fibers as they are driven flush, creating a high-stability anchor that prevents the nut from spinning when a bolt is tightened or loosened.
Constructed from heavy-duty cold-forged steel, the QTN1112 set is finished with a corrosion-resistant zinc plating for long-term durability in both indoor and humid workshop environments. The low-profile flange ensures a flush finish on the back of your workpiece, making them ideal for knock-down furniture and stem caster wheel installation. Whether you are building an adjustable-height router table or restoring a vintage cabinet, this 50-piece value set delivers the axial strength and high-torque transmission required for showroom-quality results.
- Permanent Thread Creation: Converts standard wood holes into heavy-duty 3/8"-16 machine-threaded ports.
- Anti-Rotation 4-Prong Design: Hardened steel prongs prevent the nut from twisting or stripping out the wood hole.
- Industrial Steel Construction: Provides superior shear strength compared to lighter duty hardware store alternatives.
- Zinc-Plated Protection: Chemical barrier resists rust and corrosion for long-lasting mechanical reliability.
- Versatile Material Fit: Excels in hardwoods, softwoods, plywood, and high-density particle boards.
