Roof bolts / studs are mechanically point anchored within the rock using 3 leaf bail-type expansion shells attached to the inserted end of the bolt. Expansion shells are supplied screwed onto the end of the rock tendon and are inserted into the hole. When tension is applied to the tendon the tapered plug within the shell forces the leaves to move outwards, thus wedging them against the walls of the borehole. This means that the mechanical bolt is functional immediately on installation. In many applications the installation is post-grouted for additional stability. The complete rock bolt assembly includes the threaded bar, bearing plate (washer), nut, seat and expansion shell.
Advantages of the product:
• Mechanical Anchors provide immediate active support.
• Wide choice of combinations to meet specific support requirements.
• Can be post grouted.
• The wedge and leaf arrangement provides parallel contact with the hole sides.
• Up to 4 mm range in hole diameter can be tolerated (depending on the choice of shell).

Description:
A range of four general purpose engineer’s G-clamps which have smooth running screw threads with rotatable captive pads on the lower clamping face. These clamps are finished in stove enamelled blue.
G clamps are a general purpose clamping tool which is ideal for DIY enthusiasts and can be used for many applications in both woodworking and metalworking.
G Clamps or C clamps are the simplest models designed to hold objects in place and prevent any movement. These hand tools have two jaws. The upper edge of the ’G’ acts as one jaw and a threaded screw which comes through a hole at the bottom provides the other jaw for clamping workpieces. Due to their simple build and small size they can be used almost anywhere. They are ideal for woodworking or welding.
