  • No pre-drilling

Customer Questions & Answers

could you used it for treated wood

Asked by: jojo
Absolutely. They are multi-purpose, not single purpose. They are very good and hold quite well.

#9 x 2-1/2 in. Star Drive Bugle Head R4 Multi-Purpose Wood Screw (300-Pack) is rated 4.9 out of 5 by 20.
Rated 5 out of 5 by from These do what they say they do. A tad difficult to start (for the amatuar drill/driver user) but... These do what they say they do. A tad difficult to start (for the amatuar drill/driver user) but a soft pound in with a hammer helps. Word of caution for the star drive bit (that comes with the package), there are different size bits for the different length screws. Do not try a bit from another package that is not the same length screw. I did and thought these things were useless. When using the proper bit they drive in and counter sink like a charm.

Rated 5 out of 5 by from Great deck screw I have never used these screws before but I found them to be very easy to install . The star head provides very good torque transfer and they drive smoothly

Rated 5 out of 5 by from Fantastic Screws-- I can't say enough about the durability and ease of using these screws!! They go through anything I have tried so far-- Hard wood, metal, soft wood, PVC. They drill in so smooth, the gripping and holding power of them is great.I can't imagine anything coming loose when using them!! Great product-I didn't know about them till recently from HD. I have already told some of my friends how great they are. Glad I got the 300 pack!!

Rated 5 out of 5 by from Great Screw One glance at the "engineered" look of the screw and I was curious, a 100 screws later I am convinced that it is a "better mouse trap". The split point starts easily (even in seasoned wood), the conventional section of the thread drives well, the spiral portion and "self countersink" head complement the works, with a strong hold and flush seating. The star socket is well worth making sure that you have a T-25 bit handy.

Rated 5 out of 5 by from Not just a Screw but an Engineered Fastener I love to work with wood, and that usually means joining two pieces together in some fashion. This product does not just screw wood together, it fastens them with multiple engineering tasks in one fastener. With this item, no need to pre-drill, no need to countersink, no need to worry about stripped heads or rusting. I will never buy regular deck screws again. This will save both my time and money in wasted screws.

Rated 5 out of 5 by from Great workmanship in these crews GRK is fast becoming my favorite manufacturer of high quality multipurpose screws. I have used their 3" ones for a while and they really differ from prior screws I have used. The hedd bites firmly so that it self seats in the project. They are especially useful in decking and other projects where one wants the screw to be hidden. The price is right and I plan on purchasing other sizes/lenghts from Home Depot.
