Twisted Hex Screwdriver Tip
Twisted Hex Screwdriver Tip
(OP)
Is anybody familiar with a twisted hex tip for screwdrivers? The idea is that the hex (think allen wrench) has a slight twist to it to retain the screw. We have been using tapers in the past but have heard that twists may be less susceptible to wear.
Are there any standards for this kind of thing? Does the geometry have a specific name that I should search for?
Thanks.

That does not sound very convincing, but, nor have I seen them. There is also the Bondhus Prohold hex wrenches that use a little nylonish knob at the end for bolt retention.

The other thing that happens when there is enough twist to get the parts to stick in shallow recess parts is that the bit now wants to cam out when driven in the opposite direction.
