Rated 5 out of 5 by from These are great I don't understand how someone cannot fit these with total ease. Drill the hole 6mm or in concrete maybe 6.5mm. Ensure you drill the hole a tad deeper (yes thats important)and fit them in, it is really that simple. Ensure you pull your drill bit out a few times during drilling to clean the hole. They twist in great and NEVER had one not grip 100%. Ensure you have a good T30 bit and set your drill to the lowest speed when you fit them in. Used them in every solid structure material.

Rated 5 out of 5 by from Goes Straight Into Concrete ! These screws require only a 6 mm pilot hole and NO PLUG IS NECESSARY. The Torx head (bit supplied) means there is less tendency for the driver/bit to slip or cam out and the thread all the way up lets you pull up tight provided the pilot hole is deep enough. Price is competitive. Useful when working in tight spaces to save fumbling with plugs separately. Wish I'd known about these sooner.

Rated 5 out of 5 by from Great product. Have been using these screws in all different lengths for a number of years now. Each time I use them I cannot believe how quick , easy and solid the fixings are compared to the olden days with plugs and screws . I use them a lot on fixing shuttering to concrete floors etc. so when the job is finished take them out and put them back in your screw box and use them again and again. Great product , buy them and try them you won’t be disappointed.

Rated 1 out of 5 by from Useless Brought these as opposed to chem fixing studding and bolting into concrete floor drilled to the recommended diameter hole and could only drive them in 20mm ended up having to over drill the first 70mm to get any pinch on the plates thunk I'll stick to chem fix in the future

What TX driver bit size do I need for these? TX15, TX25, TX30? You seem to sell several size driver bits but the text for the product doesn’t say which is required instead it just says TX, or am I missing something here?

EASYDRIVE COUNTERSUNK CONCRETE SCREWS 7.5 X 60MM 100 PACK (3313H) is the product I’m enquiring about.
Asked by: PRA217
Hello there, There is a star bit head provided with this item itself, you are able to use this to fit the item. It does not specify what TX size you would need specifically. Thank you for using Q&A TC
