3-1/2" Inch Robertson Square SQ # 1 Power Impact Bit 10 pack 1/4 Hex

I install commercial playgrounds and I use these pits very often. Other bits that I have purchased usually last through 1 install. I have used one for 2 installs, and it barely shows any wear. Very pleased

I use around 5000 Kreg screws a year. The regular Kreg bit would not get thru 100 screws before it started to show the tip begin to round and it would start to slip. These bits on the other hand are unbelievable. It have put in around 500 screws. I still have to wiggle it a little to get the bit out of the screw head. I bought a pack of 10 thinking these would only last a little longer than the Kreg screws. Boy was I ever wrong! With buying a pack of 10 it's going to be several years before I have buy more.

I work on RV’s for a living and 99% of the screws used in anything RV related are square bits. I had used a number of other branded bits over the years and decided to pick these up for spares Incase anyone in the shop needed one. These turned out to be better than the other bits I was using. I’m still using the same bit since the day these arrived and it shows no sign of wear. Meanwhile my diehard Snap-On fan coworker seems to sheer one of his every few weeks.Great bits and don’t have a single regret. I’d willingly pay more for these.

These are a PERFECT match for the Kreg made screws and other square head screws. I like the black anodized finish over the zinc coating myself but it’s just my personal preference and does nothing special. Great price and since my wife uses them all the time, these seem to stay in the head of the screws better for me when I’m using them at my job. YES!!! I will be buying these again since the guy I work with loses driver bits all the time.

I like how they're round and not hexagon like most

The new Simpson Strong-Tie stainless steel structural screws have a T-50 recess. (SDWS27SS) The bit in the box is not a hex bit. These bits fit perfectly in my impact driver and run these screws the way they should. The 10 pack of bits allow me to put a few with each of my tools. They seem durable and well made. I will refer these to others I know who use these new screws!

Work just as well as the ones that cost $6 each at the hardware store.

A very robust item. If they ever wear out I would purchase again without hesitation.
