Description
Overview:
Timco Winged Tip CSK Self Drilling Screws are heavy‐duty fasteners designed for reliable fixing into heavy section steel. This size 5.5 x 65 mm (approx. 0.22 x 2.56 inches) combines a sharp drill point with a winged tip that assists starting and clearance before the threads engage. Made from hardened steel with a corrosion‐resistant finish, they deliver strong hold and long service life in demanding environments. The countersunk Phillips head seats flush for a neat finish on brackets, plates, and fittings. Suitable for use with a powered drill/driver and a compatible Phillips bit, these screws drill and tap into steel up to 12 mm thick (approx. 0.47 inches), cutting installation time and helping maintain consistent results. Supplied in a pack of 200. MPN: HW65B.
Key Features:
- Winged tip assists clearance in softer materials before engaging the steel for a secure clamp
- Self‐drilling capacity into steel up to 12 mm (approx. 0.47 inches) - no pre‐drilling required in most cases
- Countersunk Phillips head for a flush, snag‐free finish under plates, hinges, and brackets
- Hardened steel construction for strength and dependable pull‐out resistance
- Precision drill point reduces walking and speeds installation with consistent starts
- 5.5 x 65 mm length (approx. 0.22 x 2.56 inches) suits thicker assemblies and stand‐off fixings
- Corrosion‐resistant finish helps protect against wear in site and workshop conditions
- Use with a quality Phillips driver bit for positive drive and reduced cam‐out
- Clean, tapered CSK head minimises surface damage and aids countersinking
- Supplied in a bulk pack of 200 for site, workshop, and maintenance teams
- Timco quality with clear reference for repeat orders - MPN: HW65B
