EXPANSION BOLTS Tapered Wedge Gives Immovable Fixing
A NEW series of expansion bolt fix- ing units has been introduced by Expandite, Ltd., Chase Road, Lon- don, N.W.10. They range from
Workshop clad in plastic coated steel
4 in. to 1 in. diameter and from 2 in, to 10 in. in length. There are two versions, the stud type and the projecting type.
The stud type Expandabolt con- sists of a standard set screw and
cone
washer, a sheradis- ed two-piece ex- panding shield and a threaded wedge. Wire cir- clips retain the whole assembly ready for immedi- ate use. The Stud type is recom- mended for ap- plications such as the fixing of heavy machinery where the equipment is project
positioned before the set screw is inserted. The action of tightening the set screw draws the tapered wedge into the expanding shield, forcing the external saw teeth of the shield into the concrete or brickwork to provide an immovable fixing.

Stud
The Projecting type operates on a similar principle, but in this case, in- stead of the set screw, a stud, screw- ed permanently into the cone wedge. is used. This type is suitable for wall fixings where the equipment can be offered up onto the projecting bolt. The fixing is then completed with a separate nut.

vised to give the finish a neat appear- ance and to be integrated with the main frame, increasing the strength and rigidity of the structure.
