12 in bar clamp for welding and fabrication
The Bessey SQ-12 is a medium-duty bar clamp built for welding and fabrication tasks. Its 12 in maximum jaw opening and 5 1/2 in throat depth suit a range of workpiece sizes. The steel handle and steel bar are designed for long service life. Weighing 6.75 lb, it provides a solid feel during clamping operations.
Standard pads protect metal, wood and composites
The clamp ships with standard pads that grip without marring surfaces. This pad type allows direct use on metal, wood, plastics and composites without extra protection. No separate jaw covers or adapters are required for these materials. The accessory set therefore keeps the setup simple for mixed-material jobs.
Steel construction and fixed throat depth
All-steel handle and bar resist bending under load and stand up to shop environments. The 5 1/2 in throat depth is fixed, so reach is consistent but cannot be extended for deeper parts. The standard pad faces are not swappable, limiting customisation for specialised jaws. Weight of 6.75 lb makes it stable on the bench but less suited to overhead use.

Questions about this item
Will the standard pads on the SQ-12 need replacing if I clamp metal and wood daily?
The standard pads are designed for metal, wood, plastics and composites without damaging surfaces; replacement depends on how abrasive your workpieces are.
At what throat depth does the 12 in bar clamp start to lose rigidity during a long glue-up?
The 5 1/2 in throat depth is the fixed limit; beyond that distance from the bar the frame will flex more under sustained clamping force.
Does the steel handle and bar get hot or heavy during all-day welding fixture work?
At 6.75 lb the clamp is substantial but manageable; steel conducts heat, so the handle and bar will warm up near a weld zone.
