Double countersunk wood screws have a two-stage countersunk head. The stronger head takes more driving torque without snapping, and the head sits flush in timber. They are general-purpose timber screws for framing, joinery, fencing and building work.
Linkworld supplies double countersunk wood screws in hardened carbon steel and stainless steel, with Type 17 or sharp points and zinc, yellow zinc, black, galvanised or Ruspert finishes. We pack in bulk cartons or in your own branded boxes, and other sizes can be made to your drawing or sample.

Where Double Countersunk Wood Screws Are Used
- Timber framing general fixing in framing and blocking
- Joinery and cabinets where a flush head is needed
- Fencing and landscaping palings, rails and garden structures
- Flooring and sheet fixing plywood and particleboard
- Outdoor timber with galvanised, Ruspert or stainless finishes
Choosing Double Countersunk Wood Screws
- Point: Type 17 cuts its own hole and reduces splitting near board ends; sharp points suit softwood and sheet.
- Ribs under the head: help the head cut into timber and sit flush.
- Drive: square and Torx give better bit grip than Phillips on longer screws.
- Finish: zinc for indoor use; galvanised or Ruspert for outdoor timber; stainless for coastal work.
Common Purchasing Mistakes
Using zinc screws outdoors. Zinc plated screws suit indoor work. Choose galvanised, Ruspert or stainless for outdoor timber.
Short screws in thick timber. Aim for at least two-thirds of the screw length in the base timber.
Mixing drives under one code. Phillips, square and Torx versions should have separate codes.
Leaving out the point type. Type 17 and sharp point screws suit different jobs. State which one you need.
