Slash Point Screws for Sheet to Timber – Exterior
Exterior coated slash point screws designed for fixing thin sheet metal to timber, providing strong corrosion resistance and reliable performance in outdoor applications.
Why choose exterior slash point screws for sheet to timber?
- Exterior coating provides long-lasting corrosion resistance
- Tested to over 500 hours salt-spray performance
- Slash point for fast pick-up into timber
- Reduces torque and helps prevent timber splitting
- Hex head with EPDM washer for a secure, weather-resistant seal
What are exterior slash point screws?
Exterior slash point screws are designed to fix thin sheet metal directly into timber without pre-drilling. The single slash point cuts quickly into timber, making installation faster while reducing the risk of splitting, especially when working close to edges.
With an exterior-grade coating, these screws are suitable for applications where moisture and weather exposure are a concern.
Where are they used?
Exterior sheet to timber screws are commonly used for:
- Cladding and roofing applications
- External sheeting and panel fixing
- Timber structures exposed to weather
- General outdoor construction and installation work
Exterior vs zinc screws
- Exterior coated screws: Designed for outdoor use with enhanced corrosion resistance
- Zinc screws: Best suited for internal use and dry environments
Exterior slash point screws are the preferred choice when working in exposed conditions where durability and protection against corrosion are essential.

Why use screws with EPDM washers?
Many sheet to timber screws are supplied with EPDM washers to help create a tight seal at the fixing point. When compressed during installation, the washer helps protect the hole around the screw and supports a more reliable, weather-resistant finish.
- Helps reduce water penetration around the fixing point
- Supports a more secure and weatherproof installation
- Ideal for roofing, cladding, and external sheeting
- Maintains flexibility in changing temperatures
Choosing the right length
The correct screw length will depend on the thickness of the sheet material and the depth of timber penetration required. For external applications, ensuring sufficient embedment into timber is important for long-term strength and stability.
