Buying Guide

Match screw size to material

Choose diameter and length (1/4" to 1/2" and 1-1/2" to 3-1/2") based on deck board thickness and metal frame engagement

Pick the right thread type

Use thread-forming screws for softer woods and thread-cutting for hard boards or pre-piloted holes to reduce splitting

Prefer star/Torx drives

Star (T-30/T-40) drives reduce cam-out and strip risk when driving long runs on trailer decks

Consider head style and countersinking

Flat heads sit flush with deck boards for a smooth surface and better load distribution on trailer floors

Check material and coating

Select hardened steel with corrosion-resistant coating suitable for road exposure and occasional moisture
