Rapid Hammer Installation
Using tiny screwdrivers on delicate signs wastes valuable labour time and increases the risk of slipping and scratching the plate surface. Hammer drive screws require no driving bit or bit socket; you simply tap them into place with a mallet or hammer, drastically reducing assembly time across high-volume production lines and field installations.
Self-Tapping Permanent Hold
Standard machine screws require pre-tapped holes, which adds extra machining steps and cost to your manufacturing process. Type U drive screws feature high-pitch spiral threads that cut their own mating thread into the parent material as they are driven home. This creates a tight, permanent grip that actively resists loosening from severe machinery vibration.
Decorative Electro-Brassed Finish
Exposed steel hardware can look out of place on brass plaques, high-end furniture, or heritage equipment. The electro-brassed plating provides a rich, warm golden hue that seamlessly complements polished brass or dark wood. It also offers a reliable layer of corrosion protection against everyday moisture and tarnishing.
Tamper-Resistant Round Head
Flat fasteners with drive slots can easily be removed or vandalized with standard workshop tools. The smooth, rounded head of a Type U drive screw has no drive socket or slot. This gives your installation a clean, finished look while physically preventing unauthorized removal once the fastener is fully seated.

Frequently Asked Questions
Can hammer drive screws be removed once installed?
Can hammer drive screws be removed once installed?
No, not easily. Type U drive screws are designed strictly as permanent fasteners. Because the head has no slot or socket and the spiral threads lock tightly into the pilot hole, removing them usually requires grinding the head off or drilling out the fastener, which can damage the surrounding plate.
Do I need to tap a thread into the hole before hammering these in?
Do I need to tap a thread into the hole before hammering these in?
No. The screw is engineered to cut its own matching thread into the pilot hole as it is hammered down. You only need to drill a clean pilot hole of the correct diameter before installation.
Why should I choose electro-brassed over standard zinc-plated screws?
Why should I choose electro-brassed over standard zinc-plated screws?
Electro-brassed screws are selected primarily when aesthetics matter. If you are mounting brass nameplates, decorative signs, or working on timber fixtures, the warm golden color of electro-brassed hardware matches the plate far better than bright silver zinc, while still providing good corrosion resistance.
