Use and selection
This sandwich-panel reference combines a hex head, a drill point and two separated thread sections. Include the panel build-up and supporting member in the connection detail so the required length and thread positions can be reviewed. Specify the finish and any washer requirements with the screw dimensions.
Catalogue size reference
| Nominal diameter | Length range / mm |
|---|---|
| M4.8 | 16-135 |
| M5.5 | 16-165 |
| M6.3 | 16-230 |
Length ranges are shown in millimetres. Confirm the exact dimensions, finish and availability when enquiring.
Reading the size reference
The M4.8, M5.5 and M6.3 rows identify nominal diameters; the adjacent figures give catalogue screw-length ranges in millimetres. For example, M6.3 is listed at 16–230 mm. The range does not specify the panel thickness it will suit, the spacing of the threaded sections or a drilling-capacity rating. Confirm these against the complete panel-and-support detail.
Compare the configuration
The double thread roofing screw is described for sheet-and-support connections. This page identifies the sandwich-panel drill-point configuration. The commercial roofing screw instead lists a #3 Phillips drive and reduced drill tip. Use the point and thread guide to describe the required thread arrangement; the products are separate configuration references.
For your enquiry
- What are the panel layers and thicknesses, and what material and thickness form the supporting member?
- Which screw diameter, length, thread positions, finish and washer arrangement does the joint drawing specify?
- What quantity, unit, packing arrangement and delivery destination should the quotation cover?
