Kreg drill jig /Goosenaugh

Never seen Kreggs before (in all my travelz)
Aware of the many and varied hex based products both with a hexagonal bolt and hexagonal hole.
Also the semi-secure screws with a star type socket.
Kreggs are square I ask if that is inherently better ?
Hex fittings etc come in multiple sizes..
I like the standard size screws with a hexagonal head and so uses a hexagonal socket usually with a cordless drill/driver.
They always seem to screw in firmly with lille risk of slipping pr mashing the head.
For a flush fitting screws with a hex socket (rather than a simple x head) woul be my preference.
I am very much an amateur so I look forward to the views of those who know.
It may be that Kreggs are indeed best for @Trigger but why not hex ?
 
In the 90s we moved Triple S to a new building and we had do build in new counters, walls new rooms, hang doors and fit internal windows etc, the week before we moved a salesman call onto the industrial estate and on us he showed us the Robertson square drive screws in different sizeds and we nough severy hundreds with the dive bits. although the work we did in the new place we never had a single screwdriver slip or head break off like you get with phillips screws, not sure you could get torx heads at that time, if you watch a lot of american or canadian joinery videos they all use them as the norm, rarely seeing a phillips or pozi.

 
Thankyou Mr Bear. !
Given that the square holed fixings come in a variety of sizes and profiles ...
i see no great advantage of hexagonal alternatives except perhaps for smaller items.
Also a slightly neater finish.
For strength I have used screws with a protruding hexagonal bolt type head.
I will look out for both square holed heads and hexagonal next time I go DIY shopping.
slippage on cross head screws and the screwdriver bit wearing has been a minor pain.
i have a clothes horse project as my next item.
using secure fixings which get countersunk would be good.

I just think of them as if sq drive in all sizes of sockets and ratchets is good enough to undo just about anything automotive it ought to be well on top of putting a screw into wood, about half of my self build had them where I need to have a seriously tight joint, I would have done all of it with them but I ran out and didn't see the pint in restocking all the sizes I needed, so carried on with torx.

The history of the square (correctly known as the Robertson) head is very interesting. It actually predates the Phillips head a little.

Quick summary ... A faster and more secure (tool wise) locating screw was needed to replace the Slot head screw (screwdriver easily slips out, damaging the surrounding surface and also slowing operations). Robertson came up with the square head which was much better with 4 good mating surfaces (and patented it).
It was Henry Ford that was primarily looking for the better screw but he was a tight-fisted bugger and wouldn't pay Robertson the fee he demanded to licence their use and ended up using the Phillips instead.
It is quite possible that if Robertson had asked for a lot less money he could have ended up better off in the end as all these Phillips screws (and the Posidrive alternative to improve on the Phillips) found on billions of things could have been square heads instead?
I would say the Robertson Square head is just as secure as the Torx and maybe as the Hex and certainly better than the Phillips. I would think 100+ years ago, the tooling to make a square head and a square bit was a lot lot easier than the much new Hex or Torx and actual manufacturing costs and possibilities must have been a key factor when designed a better head.
There are way too many screw head designs! I have a set of around 36 different bits to account for the most common different size and styles of heads ... apart from slot, phillips, pozidrive, torx, security torx, 3 sided, reverse 3-sided (you can tighten, but cannot undo) and lots of others. Just to annoy, as well as Torx, VW use either a double-6 spline head or a 12-spline head (can't recall which - you need good eyesight to tell the difference!).

PS. The square head bit is not a simple square head profile. It is slightly chamfered to allow the bit to be self-guided into the square head and sit dead straight.

Phil, Assuming you still have plans to go motorhoming in Canada, be prepared to get used to the Robertson screw - it is the screw of choice there (Robertson was Canadian) so you will certainly get familiar with it :)
 
I will check what is available here !
Torx or hexaganol post date Robbo !
It looks like they are both good.
Maybe more choice of hexagonal here.
But I appreciate the chamfer with Robbo
 
Opps! I said "VW use either a double-6 spline head or a 12-spline head" - What I should have said was not a DOUBLE-6 spline, but a TRIPLE-Square (so 12 surfaces still). Maybe the Triple-Square is 3 times as good as a Robertson :D

Triple-Square Bit. Only ever come across these on a VW and maybe a Mercedes, but they are a very secure tool fit I have to say (and of course for manufacturing, faster than the 4-sided)

Nowadays when you buy a box of assorted driver tips you usually get at least one size of sq drive tip, sometimes all three.

I think it is the #2 size which is most commonly needed, same as the Phillips #2 and PZ #2? I have lots of screwdriver bit sets and the square is very unusual to find. Always the Phillips, PZ, Slot and Torx, and often the Hex/Allen, but not the Robertson/Square.
 
Yes I think that's correctomundo.

You'd think Screwfix would sell them but I just looked.
 
I had one. Couldn't find it anywhere. Said same to Mrs Trotter ( she hates it, when I call her that).
Where was I ? Oh! Yes, I asked Mrs Trotter if she had seen it. T'was given to a lad starting carpentry apprenticeship . Glad to have helped :mad:
