Bessey Tools 660-S8 8 in Bar Clamp 4 in Throat Depth hand tool

Professional 8 in Bar Clamp for Demanding Tasks

The Bessey 660-S8 is a professional quality F-style sliding arm bar clamp built for tough jobs. Its forged steel handle provides a solid grip and the swivel pad allows for versatile use across woodworking, metalworking and fabrication projects. Delivering 726 lb of clamping pressure, it suits tradespeople and serious DIYers who need reliable holding power.

Verify Rail Size and Workpiece Dimensions

Before ordering, confirm your project fits the 8 in maximum jaw opening and the 4 in throat depth. The clamp accepts workpieces up to a nominal rail size of 7/8 x 11/32 in, so measure your material thickness and width against this specification. Ensure the sliding arm mechanism suits your workflow compared to fixed-jaw alternatives.

Consistent Pressure Over Extended Use

Under sustained load the forged steel construction resists flexing while maintaining the rated 726 lb clamping force. Replaceable standard swivel pads can be changed without tools when worn, preserving even pressure distribution during long glue-ups or fabrication holds. The 2.05 lb steel frame adds stability without excessive operator fatigue during repetitive positioning.
