Sleeper Wall and Timberlok Screws

Hi All,

I think I've decided to go with a sleeper retaining wall rather than gabions ( // ).

My plan, after reading lots of posts on here, is to set sleepers in concrete vertically and then screw horizontal sleepers to these. I'll put a vertical sleeper at each end, and one in the middle of each horizontal sleeper, if that makes sense :)

I'm planning on screwing the horizontal sleepers to the vertical ones using Timberlok landscaping screws, but my question is what size I should buy (I need to buy a LOT of them !!). Since the horizontal sleepers will be 100mm wide I was thinking of using 150mm Timberlok's which means they would go 50mm into the vertical sleeper when I screw them together - is this enough ? The alternative is to use the 200mm Timberlok's but these may poke out of the back of the vertical sleeper by a mm or so . . .

I've just bought myself a Makita BTD130F cordless impact driver to put the Timberlok's in with, so I'm hoping this will do the trick !!!

Anyone know the cheapest place to buy Timberlok landscaping screws ? The cheapest I've found so far is Bunny's Bolts ( ) - I think I'm gonna need to two of the 250 pails . . .

At Bunny Bolts online a pack of 250 150mm timberlok's is £112.13 inc. VAT. The screwfix 150mm are £111.38 for 250 (i.e. 5 packs) hence, it's less than a pound more for the Timberlok . . .

Any recommnedation on what length I should go for (150mm vs 200mm ?).

Has anyone used any of the cheaper alternatives to Timberlok ?

Looks like Screwfix do their own brand, Jewsons seem to as well - are they any good, or do you think paying the extra for Timberlok is worth it ?
used several, cant think of the ones we use at the moment. theyre all much of a muchness, i dont rate the green ones much though
Hi Thermo,

So you don't think it's worth paying the extra for Timberlok's - just use whatever's cheapest ??
