Frequently asked questions about the ROOFING SCREW 4,8X28 RR11 6K/8V PUUR 4X0,7 C3/ 250TK

What is ROOFING SCREW 4,8X28 RR11 6K/8V PUUR 4X0,7 C3/ 250TK?

ROOFING SCREW 4,8X28 RR11 6K/8V PUUR 4X0,7 C3/ 250TK is an ESSVE roofing screw with a 4.8 mm shank, 28 mm length, self-drilling tip, polyester‑coated zinc finish and EPDM washer; made for fixing profiled metal sheets to timber and for sheet‑over‑sheet installations.

What jobs is this screw suitable for?

This screw is for fixing profiled metal roofing sheets to timber battens and for overlapping sheet installations. The EPDM washer and polymer/zinc coating help protect the fixing point against moisture.

What are the screw dimensions and key specs?

Outer diameter 4.8 mm, length 28 mm, head diameter 10 mm, thread length 24 mm, 8 mm hex drive, recommended installation speed 1800–2500 rpm, colour code RR11 (green).

Can these screws be used for metal or concrete fixing?

The self‑drilling tip is for timber and sheet‑over‑sheet applications, not for direct fixing into heavy steel or concrete. Use purpose‑made metal or concrete anchors for those substrates.

What tool is needed to drive these roofing screws?

They use an 8 mm hex drive (8 mm socket/bit). Use a screwgun or drill with speed control around 1800–2500 rpm and torque control to avoid over‑tightening the EPDM washer.

What is the screw's finish and corrosion protection?

Made from hardened steel with a bright zinc plating and polyester powder coating; fitted with an EPDM washer and a galvanised steel washer to enhance corrosion resistance.

Is this screw suitable for humid or seaside environments?

The zinc + polyester coated steel version offers basic corrosion protection; for harsher seaside conditions you should use the stainless steel version with EPDM washer, which is stated as available.

What is the thread length and how does it affect holding in timber?

Thread length is 24 mm of the 28 mm screw, providing solid bite in thin timber battens while the self‑drilling tip forms the hole. This thread length is suitable for fixing profiled sheets to timber.

How to drive the screw without damaging the EPDM washer?

Use a driver with torque control and 1800–2500 rpm; tighten until the EPDM washer seals against the surface but avoid over‑tightening which will deform the washer. Ensure the washer sits flat and even.

How many screws per pack and how many per m² of roof?

The SKU indicates 250TK — the pack contains 250 screws. Screws per m² depend on your profile and fixing pattern; calculate based on the spacing and number of fastenings along sheet edges and ribs.

What is the difference between the steel and stainless versions of this product?

The steel version uses zinc plating plus polyester coating for basic protection, while the stainless steel option gives much higher corrosion resistance for harsher environments; both are supplied with an EPDM washer.
