Permanent

OneWay

One-way security screws, or clutch-head screws, utilize an asymmetrical, sloped drive geometry that permits clockwise rotation for installation while inducing cam-out upon counter-clockwise torque application. This irreversible design enables assembly with standard slotted screwdrivers but prohibits extraction without specialized destruction or extraction tools. Typically constructed from corrosion-resistant Grade 304 or 316 stainless steel, they yield a permanent, tamper-proof joint with a smooth aesthetic profile. They are predominantly employed in public infrastructure, washroom partitions, and fixed security enclosures where routine maintenance is entirely unrequired.
