Product and application brief
A wood-to-wood dowel screw is a headless connector with wood-screw threads at both ends, used to join wood components without an exposed screw head. The two wood-engaging interfaces distinguish it from a hanger bolt, which combines a wood thread with a machine thread.
Construction choices
| Choice or field | What to identify |
|---|---|
| Two wood-engaging ends | Identify thread and point geometry, threaded length and host material independently for each end. |
| Centre configuration | Specify the centre section and any selected driving feature from the drawing; no universal construction or tool is assumed. |
| Headless joint | Define the intended concealed connection and the assembly access rather than substituting a headed wood screw. |
Two host interfaces
Record the wood or wood-based material at each end, joint arrangement, thickness and required engagement. Hole preparation and installation steps must come from the selected product documentation or responsible design; no generic pilot-hole size or torque is supplied here.
Geometry and access
Identify overall length, the separate threaded end lengths, centre arrangement and point forms. Provide the assembly drawing to review alignment, clearances and the available assembly sequence. A generic illustration cannot settle manufacturing tolerances.
Distinction from hanger bolts and metal studs
A hanger bolt has one machine-threaded end for a nut or threaded component. An ordinary double-ended metal stud uses machine-thread interfaces. This page specifically concerns wood-engaging threads at both ends, not a general approval for any timber connection.
Specification fields
| Choice or field | What to identify |
|---|---|
| Identity | Selected part reference or controlled drawing and revision. |
| End A and End B | Wood-thread and point geometry, threaded lengths and host materials separately. |
| Centre and length | Overall length, centre geometry, selected drive if applicable and tolerances with units. |
| Joint | Assembly drawing, wood materials, preparation, access, clearances and approved installation requirements. |
| Order | Material, finish, quantities, destination, packing and required inspection evidence. |
Common product questions
Is this a hanger bolt?
No. A wood-to-wood dowel screw has wood-engaging threads at both ends; a hanger bolt has a machine thread at one end.
Are all dowel screws the same construction?
No. Catalogue terminology varies. Specify wood-to-wood interfaces and the exact part or drawing, including centre and point arrangements.
Does this page provide connection strength or a pilot-hole size?
No. Those requirements need the exact selected product, host materials, joint design and supporting installation or performance documents.
