Product Number: SDHX4225
Variations
When standard screws require a pre-drilled pilot hole, jobs slow down and the risk of misalignment increases. The Sealey SDHX4225 self-drilling hex head screw removes that step entirely, allowing you to drive directly into the material without preparation. Each screw measures 4.2 x 25mm, features a hex head for positive driver engagement, and is zinc plated for corrosion resistance. Manufactured to DIN 7504K, these screws meet a recognised international standard for self-drilling fasteners. The pack of 100 is supplied in a resealable bag, keeping unused fixings clean and organised between jobs.
