Twinthread Woodscrews

When you’re working on timber fixings and you need speed, grip and reliability, our range of twin-thread woodscrews is built tough for the trade. While standard woodscrews have a single helix, these screws feature two threads (aka “twin-thread”) which help drive faster, bite harder and pull even better, making them ideal for carpenters, joiners and site-hands alike. 

Whether you’re securing stud work, love-lining boards, installing skirting, fixing plywood or tackling general timber assembly, twin-thread woodscrews bring clear benefits: faster drive-in time, fewer driver slips and improved holding power in soft and standard timbers. Many are designed with a sharp point start and deep twin helix which mean you get quick engagement and less tearing or splitting of timber. 

We stock trade-packs of sizes, finishes and head types to match your toolbox: countersunk heads for flush finishes, Pozi or TX drives to suit your driver bits, zinc or coated finishes where corrosion resistance matters. From small repairs to large-scale joinery jobs, our twin-thread range gives you a screw you can trust to go in clean, hold firm and leave you confident in the result. On-site, that means less fiddling, fewer callbacks and a job done right the first time. Stock up your van with twin-thread woodscrews and let every fixing be the strong link.

FAQs 

1. What exactly is a twin-thread woodscrew?
   

   A twin-thread woodscrew features two helical threads instead of one. This design increases penetration speed, improves pull-out resistance and gives a better grip in timber compared to single-thread screws.

2. When should I use twin-thread over regular woodscrews?
   

   Use twin-thread screws when you want faster drive-in, stronger hold and tougher performance, for example, in joinery, fixing boards, or jobs where the fixing may be subject to movement or load. They’re especially good in soft to medium timbers.

3. Do I need to pre-drill when using twin-thread screws?
   

   In many cases, you will not need to pre-drill, because the twin threads aid faster entry and better grip. However, for very hard timber or when working near edges or with large-diameter screws, pre-drilling is still good practice to avoid splitting.

4. Are they suitable for outdoor or damp-environment use?
   

   Yes, but as always, you’ll need to pick the correct finish. Twin-thread woodscrews with corrosion-resistant coatings or stainless finishes are appropriate for damp, exterior or high-moisture environments. Always check the product specification.

5. Do twin-thread woodscrews work with other materials besides timber?

They’re primarily designed for wood and wood-based materials (e.g., MDF, chipboard). Some can be used in conjunction with plugs for masonry or other substrates, but for metal or specialist substrates, you should use a screw designed for that material.
