\XilIGHT and time are but two of e savings effected, by the "speed nut," a new product of Simmonds Aerocessories, Ltd., Great West Road, Brentford. It is shown in an accompanying sketch and it will be seen that, in one case, it is applied to a plain .pin and, in the other, to a screw, and that it consists of a thin piece of metal which actually is spring steel.
Doubtless some engineers will be horrified at the thought of replacing a nut with such a device, but, for suitable purposes, it is claimed to function wholly successfully and there is, indeed, no reason why it should not. When pushed up tight on a plain pin and tapped home, it cannot be pulled off. Even on polished steel bar it is said to hold securely. Used with a screw, the fixing can be undone in the ordinary manner. Speed of assembly, low cost and lightness give the "speed nut" big attractions, and, as it cannot come loose through vibration and makes a really tight joint, there must be countless applications where it will show superiority over a conventional nut and bolt, or rivet.
Full particulars and evidence of its efficiency can be obtained from the concern named above.
