Frequently asked questions
How do I size construction screws?
Choose diameter, length, thread or gauge from the materials, load and connection design. Follow structural or manufacturer requirements where applicable.
Does stainless steel always prevent corrosion?
No. Stainless grades vary and galvanic compatibility matters. Exterior and treated-lumber applications can require specific coatings or materials.
Can I substitute one fastener type for another?
Not for structural or specified connections unless the replacement is approved for the application.
What head or drive style is best?
Choose for tool access, torque transfer, finish and whether the fastener needs to sit flush, proud or under a washer.
Do pilot holes matter?
They can reduce splitting, control location and installation torque. Follow the fastener maker's recommendations for material and diameter.
How should shop fasteners be stored?
Keep sizes and grades separated, labeled and dry so visually similar hardware is not accidentally mixed.
What should I verify before ordering?
Confirm dimensions, material/coating, strength grade, quantity and any required code or evaluation-report approval.
