Screwfix Prices Then And Now

Not so; I think you may be confusing Pozi and Phillips. Phillips are designed to cam out because they have angled sides and are found in industrial application where a machine is driving the screw, so pressure and angle are consistent and the robot needs the screw to separate easily from the bit when it's done driving

Ah - OK - thanks.

Keep a stock of PZ2 bits and swap em out if they've bounced around inside too many screws or look visibly propellered

I do know I'd much rather have soft bits which get bollixed when they slip, and can easily be tossed, than hard bits which bollix the screwhead.

Pozidriv is designed to cam out. It's a feature.

Well, lucky old Pozidriv users! It certainly works.

I saw an article some time ago, that claimed Phillips was designed to chew up - rather than the screw snap - as early machines had poor / no torque clutches.

Sacrifice the screw head during the assembly process, rather than the screw itself (buggering up the assembly itself).

I purchased a corded sds drill in the late 90”s from Screwfix, it’s cheaper now, presumably because Bosch shifted production to the far east
