Full title and description

Standard Specification for Round Wood Dowels (Pegs) for Use in Wood Construction — a concise ASTM specification that standardizes dimensions, materials, tolerances, and basic manufacture/finish requirements for round wood dowels used as connectors in wood construction assemblies.

Abstract

This specification defines accepted diameters, dimensional tolerances, material and manufacture requirements, drying and species limits, and basic surface treatment for round wood dowels (pegs) intended for structural and non-structural wood connections. Key elements include diameter range, maximum allowable variation along the dowel, fiber orientation, minimum oven‑dry specific gravity for permitted species, drying practice, and use of a moisture‑inhibiting surface seal.

General information

• Status: Active / Current.
• Publication date: February 1, 2023 (approved).
• Publisher: ASTM International.
• ICS / categories: Timber and wood products; commonly cataloged under ICS code for semi‑manufactures of timber (example listing: 79.080).
• Edition / version: D8023‑23 (current 2023 edition). Replaces D8023‑17.
• Number of pages: 2 pages (concise, specification‑length document).

Scope

The specification standardizes dimensions and materials for manufacture of round wood dowels (pegs) used in fabrication of connections in wood construction. It is intended to give designers, fabricators, purchasers, and regulatory bodies assurance that dowels meet minimum materials and dimensional quality so connection performance can be relied upon. The standard addresses only round dowels (not sawn or cleaved pegs) and uses inch‑pound units as normative.

Key topics and requirements

• Diameter range: nominal diameters from 1/2 in. (≈12.5 mm) up to 2 in. (≈51 mm).
• Dimensional tolerances: diameters shall not be more than 2% oversize nor less than 1% undersize; longitudinal variation (excluding chamfer) limited (typically ≤1%).
• Fiber orientation and manufacture: dowels must be fabricated so wood fibers are aligned with the longitudinal axis (to preserve strength and predictable connection behavior).
• Material/species limits: dowels shall be fabricated from species having an oven‑dry specific gravity of at least 0.57 (determined per Test Method D2395); species‑designated dowels must meet minimum species gravity requirements.
• Drying: material should be air‑dried or kiln‑dried to approximately constant weight before fabrication to reduce dimensional instability and moisture‑related defects.
• Condition and defects: dowels shall be clear, straight‑grained, free from decay, and not brittle or otherwise difficult to install.
• Finish/protection: dowels should be protected with paraffin wax or a similar sealing substance to inhibit atmospheric moisture absorption.
• Units and conversions: inch‑pound units are normative; SI conversions, if given, are informational only.

Typical use and users

Used by wood product manufacturers, joinery and furniture shops, timber‑connector producers, structural timber fabricators, architects, engineers, building inspectors, and procurement/specification writers who require standard, reliable dowel dimensions and basic material quality for connections in wood construction. Also used by code bodies and testing laboratories as a reference for acceptability of dowels encountered in the field.

Related standards

References and related documents commonly cited include ASTM Test Method D2395 (density/specific gravity of wood) for determining oven‑dry specific gravity, the National Design Specification (NDS) values referenced for species gravity, and other ASTM wood committee documents under Committee D07 (Subcommittee D07.05 on Wood Assemblies). The 2023 edition supersedes D8023‑17.

A: ASTM D8023‑23 is the 2023 ASTM specification that standardizes dimensions and basic material/manufacture requirements for round wood dowels (pegs) used in wood construction connections.

Q: What does it cover?

A: It covers nominal diameters (½ in. to 2 in.), tolerances, allowable variation along dowel length, fiber orientation, minimum oven‑dry specific gravity for permitted species, drying practice, condition (clear, straight‑grained, decay‑free), and simple surface protection (e.g., paraffin). Inch‑pound units are normative.

Q: Who typically uses it?

A: Manufacturers of dowels and wooden connectors, timber fabricators, joiners, structural designers and specifiers, building officials, and purchasers who need concise, reproducible requirements for dowel materials and dimensions.

Q: Is it current or superseded?
