POWERTEC 71168-P2 T-Track Hold Down Clamp, 5-1/2” L x 1-1/8” W, 4

The POWERTEC 71168-P2 T-Track Hold Down Clamp pack provides four complete workholding assemblies for woodworking and metalworking machinery. Designed for standard T-track systems, these clamps secure workpieces firmly during cutting, shaping, and drilling operations across various shop setups.

Each clamp is constructed from anodized aluminum with a lever-shaped profile. This curved design delivers strong clamping leverage while keeping the clamp body clear of your cutting path and hands. Non-marring pads on the clamping ends prevent dents and surface damage on your material, while ergonomic five-star knobs make tightening and releasing tension smooth and straightforward.

Compatibility is an important factor to consider before purchasing. The included T-bolts measure 5/16-inch-18 by 3-1/2 inches, featuring bolt heads that are 17/32 inch wide, 13/16 inch long, and 7/64 inch thick. They fit Universal T-tracks or larger tracks, meaning they are not compatible with smaller 1/4-inch or Mini T-track profiles.

Verdict: This four-piece hold-down clamp set is a solid, reliable choice for woodworkers and machinists needing dependable workholding across CNC tables, router fences, drill presses, and jigs. As long as your tracks accommodate standard Universal T-track bolts, these clamps offer an efficient way to keep your stock securely in place.
