Bessey Tools SQ-20 20 in Bar Clamp 5 1/2 in Throat Depth 660 lb Force

20 inch bar clamp for industrial use

The Bessey SQ-20 bar clamp provides a 20 in clamping capacity and 660 lb of force for heavy-duty holding tasks. Its 5 1/2 in throat depth allows reach over wide workpieces. A steel bar and steel handle deliver the rigidity required in industrial environments. The standard jaw pads measure 1 1/2 in wide to distribute pressure evenly.

Sustained clamping behaviour under load

The 5/8 in thick steel bar resists bowing when the spindle applies maximum force across the full 20 in span. A 13/16 in spindle diameter transmits torque without flex, keeping pressure consistent during long glue-ups or fabrication holds. The bar slide mechanism maintains alignment so the jaws stay parallel under continuous load. Steel handle construction prevents the flex that reduces effective force over time.

Build quality and daily mounting implications

Overall width of 8 1/4 in fits between common fixture spacings while the 4 5/8 in handle length gives leverage without excessive swing radius. At 8.2 lb the clamp is substantial enough to stay planted yet light enough for frequent repositioning. Steel bar and handle surfaces withstand shop abrasion and repeated tightening cycles. Standard jaw pads can be replaced or supplemented with custom faces for specialised work.
