Description
Product Overview
The Mardatt 1/4‑20 Thread Tee Bolt Set is engineered for precision, durability, and ease of use in a wide range of industrial and hobbyist applications. Each bolt is forged from high‑grade carbon steel and then zinc‑plated to provide superior corrosion resistance, ensuring a long service life even in humid or oily environments. The set contains 40 pieces distributed across five standard lengths—1″, 1‑1/4″, 1‑1/2″, 1‑3/4″ (5 pcs), and 2″ (5 pcs)—allowing you to select the exact size required for any T‑slot track or fixture. The T‑shaped head is specifically designed to sit flush within the T‑slot groove, delivering a secure fit while preventing stripping during tightening. All dimensions conform to the 1/4‑20 thread standard, making these bolts compatible with a broad array of T‑nuts, knobs, and other fastening accessories commonly used in aluminum extrusion systems, modular furniture, and CNC router fixtures.

Usage
These bolts excel in woodworking jigs where precise positioning and repeatable clamping are essential. Whether you are building a custom router table, assembling a cabinet frame, or constructing a modular workbench, the Mardatt tee bolts provide the stability needed to keep your workpiece firmly in place. The set is also perfectly suited for aluminum alloy rack assemblies used in industrial shelving, laboratory equipment, and lightweight structural frames. Because the bolts are zinc‑plated, they resist rust when used in outdoor or marine‑adjacent projects, making them a reliable choice for outdoor workshop benches, garden tool storage units, and even boat‑deck fixtures. The variety of lengths ensures you can accommodate different material thicknesses, from thin plywood panels to thick hardwood slabs, without compromising on torque or alignment.
