By Dr Bill Eccles, Bolt Science It is considered by some that the screw thread was invented in about 400BC by Archytas of Tarentum (428 BC - 350 BC). Archytas is sometimes called the founder of mechanics and was a contemporary of Plato. One of the first applications of the screw principle was in presses for the extraction of oils from olives and juice from grapes. The oil presses in Pompeii wer...

norelem’s range of ball lock pins provide added reassurance to engineers where dependable high shear strength is most needed.

REYHER has introduced a new bit series - Tight Bits, which prevent the tool from slipping out of the screw head. This makes overhead work, much easier.  Most users of hexagon socket screws are familiar with the problem. The relatively large leeway between screw and bit leads to a tumbling motion when screwing, or the bit slips out of the screw head. REYHER’s new Tight Bits with wider, stronger...
