Bessey STC-HA20 Horizontal Toggle Clamp

The Bessey STC-HA20 is a steel horizontal toggle clamp designed for repetitive holding tasks. It features a U-bar arm with a polyethylene tip and a 180-degree opening angle. The clamp mounts via front-facing holes spaced 1.02 inches apart on centre. A plastic protective cap is included with the unit.

Suits fixtures needing quick horizontal locking

This clamp suits jigs and fixtures where a horizontal handle saves vertical clearance. The auto-adjust mechanism accommodates workpiece variation without manual resetting. Buyers who need a vertical handle orientation or a locking handle for vibration security should look at alternative clamp styles. The 450 lbf holding capacity fits light to medium clamping jobs.

Questions about this item

How much clamping force does the 450 lbf holding capacity deliver in use?

The clamp applies up to 250 lb of clamping force while the holding capacity is rated at 450 lbf.

What does the M6 fastener thread size limit for mounting?

The M6 thread size means the clamp must be bolted with M6 hardware; it caps the bolt diameter you can use for installation.

How much space does the 1.77 in arm and 0.79 in height need to fit?

The U-bar arm extends 1.77 in and sits 0.79 in above the base, so allow at least that clearance for the clamp to operate.
