Metalworking Bar Clamp for Assembly and Machining
The BESSEY MMS-4 is a steel bar clamp built for metalworking tasks such as assembly, gluing and machining. Its profiled rail adds strength and travel while accepting compatible accessories. A sliding T-style steel handle provides grip and adjustment control. Swivel-type jaw pads adapt to varying angles and surfaces for versatile workpiece holding.
4-Inch Capacity and 400-lb Force Define Practical
The clamp delivers a nominal clamping force of 400 lb across a maximum capacity of 4 in. Throat depth reaches 2.25 in, setting the maximum reach from the bar to the workpiece face. These figures determine the size of stock that can be secured and the pressure available for holding during machining or glue-up operations.
Handles Small to Medium Workpieces.
The tool comfortably secures narrower stock within its 4-inch span and 2.25-inch throat depth for typical bench tasks. Builders needing to clamp wider panels or deeper assemblies will find the reach insufficient. The 400-lb force suits general metalworking but may fall short for heavy structural joints requiring higher pressure.

Questions about this item
Which Bessey bar clamp capacity matches my workpiece width?
The MMS-4 model provides a 4 in clamping capacity, so choose it when the distance between jaws must reach four inches.
What does the 400 lb nominal clamping force mean on the bench?
It indicates the maximum pressured grip the steel bar and sliding head can apply to a workpiece during assembly or machining.
How does the 2.25 in throat depth limit reach on a wide panel?
The clamp can only exert force up to 2.25 in from the bar edge, so material wider than that cannot be clamped centrally.
