Hex Cover Caps

Cover caps are a perfect way to blend in roofing and construction screws with coloured panels. Please bare in mind we only stock a certain amount of colours, please allow at least one week for dispatch. Poppy red caps are used for highlighting weaker transparent sheets.

EPDM Washer 

Metal washer with rubber (EPDM) used to prevent washer ingress.

BAZ Washer

Heavy duty and high grade EPDM washer with A2 stainless steel cap to provide a water-tight seal. Also known as a BAZ washer. Frequently used with self-drilling screws in roofing applications.

Sela Washer & Cover

Used when securing roofing sheets to create a watertight seal. When using spring head roofing nails just a washer (SW) is required. If using hook bolts you will also require a Sela Cover (SC) to cover the washer and nut to complete the seal.

Dowty Type Washer

Used mainly with drive screw nails and spring head roofing nails for attaching corrugated roofing sheets to wooden purlins. The washer provides a watertight seal when used correctly.

Corrugated Sheet Fixing

Designed for fixing plastic corrugated sheets to timber. The hinged cover cap provides a tight seal to prevent water ingress. Spacers should be used with strap caps when fitting corrugated sheeting to prevent splitting of the sheets as the fixings are tightened.
