T-Head T-Slot Bolts & Square Head Bolts - Industrial Fasteners for T-Slot Rails, Machinery & Structural Assembly

Square head bolts are used in applications where visibility is limited but durable fastening is required. These bolts have large, flat sides and are easy to tighten with a wrench. Square heads are best used in tight or dark spaces where a machinist or fabricator must tighten the bolt blind.

This product line includes two specialized fasteners: T-head T-slot bolts and square head bolts, both engineered for secure, adaptable fastening in industrial and mechanical scenarios. The T-head T-slot bolts feature a unique T-shaped head that slides into T-slot rails (common in workbenches, machine tools, or aluminum profiles), allowing for adjustable positioning before tightening—this design eliminates the need for nuts on one side, saving space and simplifying assembly.
