Wilton 660S-8 8 in Bar Clamp 4 in Throat Depth tool storage

Light-Duty F-Clamp for Trade Work

The Wilton 660S-8 is a light-duty F-clamp built for automotive, metalworking, plumbing, welding and woodworking tasks. It uses an extruded steel bar with a fixed head and an adjustable sliding head to apply pressure across a workpiece. The clamp delivers up to 660 lbf of clamping force when fully tightened. Replaceable V-groove jaw pads maintain secure contact during gluing, fastening or machining operations.

Suited for Light Assembly and Glue-Ups

This clamp suits technicians and hobbyists who need moderate reach and force for smaller workpieces. The 8-inch maximum jaw opening and 4-inch throat depth limit its use on wide or deep assemblies. Builders who need higher clamping pressure, longer reach or greater throat depth should look at heavy-duty bar or pipe clamps instead. The hex-head swivel simplifies adjustment but does not replace a dedicated quick-release mechanism.

Fits a Bench Setup With Steel Bar Rigidity

The 3/8-inch thick by 3/4-inch wide steel bar adds stiffness to a bench-top clamping station without excessive weight. Its fixed-head design anchors one end while the sliding head moves along the bar, freeing the user’s hands for alignment. No external power or accessories are required; the clamp works standalone once positioned. The replaceable pads extend service life in environments where jaw faces wear quickly.
