Why the Right Screw Matters

Using the wrong screw size can cause permanent damage to your hardware. A screw that is too long can puncture components, crack motherboards, or push through chassis. A screw too short will not hold, and the wrong thread diameter will strip threads in their seats and ruin standoffs.

• Wrong length: punctured PCBs, cracked housings, broken battery cells
• Wrong diameter: stripped threads in standoffs and inserts
• Wrong drive type: cammed-out heads and unrecoverable fasteners
• Wrong finish: corrosion and rust over time
