Lightning fasteners

[HowardH]

I know it's hard to get excited about fasteners but I saw a demo on these construction screws on Youtube.  I have used GRK's for years and the biggest issue I have is they won't grip the bit so I'm constantly dropping them.  This system from Phillips eliminates that.  I haven't seen where they sell them yet other than an assortment box on Amazon but if I can find a supply, they will be my go to fastener from now on.

Wow, just want we need, another screw head system.  The current ones are:

I was just getting used to Pozidriv.

Dead on arrival.

Of course it's made by the same company who brought us phillips screws, which causes everyone else to develop screws to solve the issues of philips screws.  And then they made Pozi, basically to get a new patent going, Pozi took off in Europe, not much else where, and now that same company tries yet again and boost about how it's patented (proprietary).

Torx has won.  Soon as the patents expired, everyone adopted them globally and they all ready do what this is trying to do, they are all ready designed for machines to drive them.  Standards orgs like ASME has had torx (star drive) in the spec for several years now, most all screws come in torx.

There is always room for a superior fastener especially if it’s competitively priced and easy to get. It’s still early for these but the OP is interested because the GRK Torx screws annoyingly fall off the driver.

Phillips head screws were a great invention at the time (like in the 1930's) and they made a huge impact on automobile assembly and automated assembly in general.  The self centering feature was crucial for production line efficiency and the cam-out feature was also nice.

However...that's where it should have ended.  That drive style should never should have been allowed in the mainstream fastener market.

I read an interesting study where screws with Phillips and Torx drives were subjected to tightening/loosening cycles at a predetermined torque level. The Phillips bit was only useable for about 1500 uses while the Torx bit was useable for 20,000 uses.

Something to think about when that Phillips bit starts to slip a little. Just toss it and use a new one because it's life is limited by the drive design.

And Phillips screws have a very short life cycle compared to Robertson etc. When I disassemble old jigs and fixtures if the fasteners are Phillips I just toss them. If square drive or Torx they go into a bin for re-use.

Pretty sure we have had those over in the UK for at least seven years, under a different name but the same anti cam out ridges, the same square centred philips drive and the same cut in the thread.

Bullet screws if I remember right, even the box was well made as it opens up like a drawer.
