M6 Dowel Screws (Wood-to-Metal) are manufactured to Trade series (double-end wood screw). This page lists the controlling dimensions for the M6 size together with the drive and the installation notes for this type.
Values are taken from the governing standard rather than from a general machine-thread table, because this type is not selected on one.
M6 Dimensional Row (Trade series (double-end wood screw))
| Machine thread | Wood end nominal (mm) | Overall length (mm) | Wood end length (mm) | Machine end length (mm) | Pilot hole in hardwood (mm) | Material |
|---|
| M6 | 6.0 | 50 | 25 | 20 | 4.0 | Steel zinc plated |

Need dowel screws (wood-to-metal) in a size this table does not list?
This page covers M6 dowel screws (wood-to-metal). A non-standard screw is quoted from the drawing; where one already exists in the catalog, the special is usually a variation on its tooling. Made by cold heading or warm forging.
Minimum order from 2,000 pieces; samples within 7 days of drawing approval.

Applications & Industries for M6 Dowel Screws
Where Dowel Screws are used, and what decides the specification in each case. Stocked from M5 to M10.
Industries that specify Dowel Screws
-
Joinery & furniture
Hardware, hinges and fittings into solid timber and wood-based board.
-
Roofing & cladding
Profiled sheet and rainscreen fixed to purlins and rails.
-
Volume assembly
Appliance and consumer products driven at speed with power tools.
-
Construction & fit-out
Fixing board, batten, framing and trim into timber and light-gauge steel.
-
Sheet-metal & HVAC
Ducting, enclosures, trunking and cladding assembled without tapped holes.
Typical applications
- high-volume driving with a bit and a clutch-set driver
- forming a thread directly in sheet, board or timber
- fixing where there is no access to add a nut behind the panel
Service conditions to specify against
- Marine and coastal
- Available in A4 (316) stainless for chloride exposure — coastal structures, pool halls, water treatment and deck hardware, where A2 will eventually pit.
- Pilot hole
- Selection is really a hole-size decision: too small and the screw snaps or splits the material, too large and it strips. The size is stated per row.
Where to use something else
- Not for a joint that will be dismantled and reassembled repeatedly in the same hole — use an insert or a rivet nut instead.
