Description

Material
Steel.
Version
Case-hardened (56 ±1 HRC) and blue galvanised.
Grade 8.8
Note
Robust, compact spiral cam clamping screws that exert a positive down force on diverse workpiece forms.
Assembly
Drill and tap several holes at a distance X or Z (see diagram). Screw the cam screw into the required height and position with the flat side to the workpiece. Position the workpiece and tighten the cam screw with a hexagon key. Full clamping is achieved with approximately a 1/3 rotation. Lubricate the tapped hole regularly.

Place stops on the face towards which the screw turns to prevent the workpiece rotating away.
On request
Spiral cam screws with LH thread.
Drawing reference
1) clamping sheet metal
