Product and application brief
A hanger bolt combines a wood-screw thread at one end with a machine thread at the other. Define both interfaces separately: the wood end engages the specified host, while the machine end mates with the specified nut or threaded component. This is not an ordinary machine-threaded double-ended stud.
Construction choices
| Choice or field | What to identify |
|---|---|
| Wood-to-machine-thread construction | Identify both thread systems, threaded lengths, overall length and any intermediate shank. |
| Drive arrangement | Catalogue constructions may use different drive arrangements. Supply the selected reference or drawing rather than assuming a drive or compatible tool. |
| Catalogue example | Fastenright identifies an external-hex-drive wood-to-metal dowel. It is one construction example, not a universal hanger-bolt geometry. |
Two different mating interfaces
Specify wood or wood-based host material and the controlled host-hole and engagement requirements. Independently specify machine-thread diameter, pitch or TPI, hand, fit and mating component. Matching one end does not qualify the other interface.
Connection and access
Provide an assembly drawing showing host thickness, edge distances, machine-end projection, nut or component clearance and access. Any preparation or installation procedure must come from the selected product documentation or responsible design; no generic pilot-hole size or torque is stated here.
Not a universal timber or structural approval
This page describes a construction family. It does not establish load rating, pull-out resistance, structural qualification, corrosion performance or suitability for a roof, ceiling or other safety-related connection. Those requirements need the exact selected product and applicable evidence.
Specification fields
| Choice or field | What to identify |
|---|---|
| Identity | Selected part reference or controlled drawing and revision. |
| Wood end | Thread and point geometry, threaded length, host material and approved preparation. |
| Machine end | Thread system, diameter, pitch/TPI, hand, fit and mating component. |
| Geometry | Overall length, end lengths, intermediate shank, drive, clearance and drawing tolerances with units. |
| Order | Material, finish, quantities, packing, destination and required inspection documents. |
Common product questions
Is this an ordinary double-ended stud?
No. A hanger bolt combines wood-thread and machine-thread interfaces; an ordinary machine-threaded stud does not establish the wood interface.
Does the illustration confirm drive or dimensions?
No. It is a generic AI appearance reference. The selected drawing defines drive, dimensions and thread lengths.
Can thread size alone establish suitability?
No. Both mating interfaces, host conditions, connection geometry and required evidence need separate review.
