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.
