Metal connectors such as beam supports, brackets, and perforated plates are essential components in modern wood construction.
To ensure reliable structural performance, these connectors must be installed with appropriate structural fasteners..
Structural connector screws are specifically developed to secure metal connectors to wooden structural elements, providing quick installation and safe load transfer.
What are Structural Connector Screws?
Structural connector screws are fasteners designed for steel-wood structural connections..
Unlike common wood screws, they feature:
reinforced heads for metal plates,
optimized structural threads,
self-tapping cutting tips,
high torsional strength,
and a Torx drive for professional installation.
These features allow for the safe transfer of structural loads from the metal connector to the wood..
Typical Applications
Connector screws are commonly used in:
joist hangers
structural brackets,
beam connectors,
perforated plates,
reinforcement plates,
post bases and column connectors
timber-to-concrete steel connectors
They are suitable for installation in:
solid structural timber
glued laminated timber
CLT
LVL
This makes them ideal for wood structures, roofs, and engineered wood construction.
5 mm vs 8 mm Connector Screws
The two most common diameters used in metal connectors are 5 mm and 8 mm.
5 mm Connector Screws
Used in standard connectors such as:
joist hangers
light brackets
perforated plates,
They provide quick installation and reliable structural performance.
8 mm Structural Screws for Connectors
Used in more demanding structural applications:
large brackets
post bases and column connectors
beam connectors,
structural metal plates
They offer greater load capacity and more robust structural connections.
Screws vs Nails for Connectors
Traditionally, metal connectors were installed with ring nails.
However, structural screws are increasingly used in modern construction.
Advantages of screws for connectors:
faster installation with power tools
better control during application
lower risk of wood splitting
easy adjustment or removal
high structural performance
For many professionals, screws representa more efficient and precise solution.
How to Choose the Right Screw
When selecting screws for connectors, consider:
the diameter of the connector holes
structural load
thickness of the wood
type of connector
installation conditions
The correct choice ensures that the connection meetsthe structural requirements of the project.
Structural Fastening for Wood Construction
Screws for structural connectors are an essential solution for modern wood construction, offering reliable performance and efficient installation.
They are widely used in:
wood structures
roofs
pergolas and outdoor structures
wood engineering construction
structural carpentry
