The Unifix A2-304 Tamper TX Machine Screws are essential for professionals and DIY enthusiasts who require high-security fastening solutions for sensitive equipment or public installations. Crafted from durable A2-304 stainless steel, these screws offer excellent corrosion resistance and a button head design that thwarts unauthorized removal. While they provide superior security, users should note that they require specific tamper-resistant driver bits for installation and maintenance rather than standard screwdrivers.

Yes, the A2-304 stainless steel provides excellent corrosion resistance, though for direct saltwater immersion, a higher grade like A4-316 may be preferred depending on the specific location.
These screws feature a standard button head profile designed to be compact while providing high shear strength.
No, these are tamper-resistant TX screws which feature a central pin. You must use a corresponding tamper-resistant bit that has a hole to accommodate that pin.
A2-304 stainless steel is generally non-magnetic in its annealed state, though slight magnetism can occur due to the cold-working process during manufacturing.
This product is supplied in a bulk box of 1000 units.
Ensure the driver bit is fully seated into the screw and not tilted. Check that the bit size is exactly matched to the TX specification.
Verify the receiving hole is properly tapped for M5 threads. If resistance is high, back the screw out and clear any debris from the hole.
To install these screws, ensure you have the correct size TX tamper-resistant bit that matches the internal pin configuration of the screw head. Do not use excessive force with power drills to avoid stripping the drive.
