Reisser r2 screws csk – part thread – yellow

Reisser R2 part thread screws are among the most trusted woodscrews used on site in the UK. The R2 has been the go-to choice for joiners, carpenters, and general builders for over 30 years, and it’s earned that reputation by doing exactly what a screw should do — drive cleanly, hold firmly, and not snap on you halfway through a job.

The part thread design is the key difference from a full thread version. With thread only on the lower portion of the shank, the upper section pulls the top material tight against the substrate, making it the right choice when you need two pieces of timber to draw together properly. Full thread screws grip throughout, which is great for sheet fixings, but when you’re joining timber to timber and want genuine clamping action, part thread is what you reach for.

What Makes the Reisser R2 Part Thread Screw Stand Out

The 25-degree needle point drives into most timbers without a pilot hole, which saves time when you’re working through a stack of framing. The sharp, wide thread with Reisser’s own lubrication gives up to 40% less driving resistance compared to uncoated alternatives, so your drill battery actually lasts the day. Specially hardened steel gives the R2 high tensile and torsional strength, and the thread pattern delivers strong pull-out resistance once the screw is home.

The deep reinforced Pozi countersunk head recess is worth mentioning. It gives a tight fit to the driver bit, which reduces cam-out and adds strength at the junction between shank and head. The yellow tropicalised coating provides better corrosion resistance than a standard bright zinc plated finish, making these suitable for a wide range of timber applications including treated wood.

Available in a broad range of sizes and pack quantities, from consumer packs through to bulk outer cases, so you can buy what suits the scale of the job.
