The BESSEY GSM40 classiX Regular-Duty All-Steel Bar Clamp offers medium-long reach capacity and heavy holding power for metalworking professionals and industrial fabricators. Providing up to 2,660 lbs. of clamping force across a 16 in. opening width with a 5-1/2 in. throat depth, this F-clamp is built for securing larger steel weldments, frame assemblies, and heavy metal plates.

The GSM40 is constructed using a high-tensile, heat-treated steel profile that maintains rail straightness under full clamping tension. Its hardened ACME threaded spindle is engineered to withstand shop abuse and resist weld spatter adhesion. Complete with a heavy-duty pressure pad and an electro-galvanized sliding T-bar pin handle, the GSM40 ensures effortless positioning and high pressure transfer for daily production welding.
