Rated 4 out of 5 by from Green oak sleeper fixing These screws took some driving but managed with a mains 110v sds size drill. We were screwing through green oak though. No pilot holes needed but my 1/2inch impact driver wouldn't do it. (300ib/ft) and that takes off wheel nuts easily.

Rated 5 out of 5 by from Sleeper screws Great screws for fixing 100mm sleepers to base of a fence around a parking area. Comes with the appropriate sized nut driver too so very simple to use and went through the pilot hole and into the upright with ease when using an impact driver. No idea on durability but look well made. I bought some long 6mm drill bits too for the pilot hole through the 100mm sleeper - worth it if you only have a basic drill bit set.

Rated 2 out of 5 by from Not great Did not pre-drill and didn't go in with my impact driver

Rated 1 out of 5 by from They Will Burn Your Drill Out! Even with a corded drill they would not go through the sleepers and burnt the drill out. Not recommended.

Will these work with new green oak sleepers?

Can these go straight in or is a pilot hole needed?
Asked by: jdrdiy
Hello jdrdiy, Thank you for your question. With a good quality 750W power drill and 1/2" chuck, you will have no trouble drilling these straight into your sleepers. If you have a lower power drill or less powerful cordless, you may find a pilot hole an advantage to assist the drill.

Can you use these with an angle bracket?

I'm screwing together sleepers for a raised flower bed. Thanks.
Asked by: Neil7
Hello Neil7, Thank you for your question. The Timberlok range is designed as a timber to timber fixing and will self-countersink into the sleepers. We recommend fixing the sleepers to each other directly with our longer Timberlok screws (also available from Screwfix) and avoiding using brackets, this should leave you with a cleaner and more natural look.

Are these suitable for use in Green Oak?

I know that usually stainless steel or brass is recommended for use in Oak as the sap can corrode steel. But are TimberLok (and HeadLok) suitable?
Asked by: Jez78
Hello Jez78, thank you for your question. Timberlok and Headlok screws are coated in a proprietary black solution by a very specific multi-step process that gives them a very high corrosion resistance, even in green oak. The final layer, a clear top coat, also serves as a lubricating layer to assist you in driving them into harder timbers.

What size hex bit do I need for these?

Asked by: Albesan
The hex bit is supplied with these screws - so you don't need to buy it separately.
