2 Hole Pig Nose Fixings
Pig nose (or 2-hole) fixings are security fasteners with two holes drilled into the head of the fasteners which are used to fasten and remove them, with a special insert drive bit.
Also known as pig nose screws, snake eye security screws, pig nose fixings, two pin and spanner drive screws, these security fasteners provide an aesthetic medium security solution at relatively low cost, ideal for use in public areas.
The two holes can be drilled at different distances (between centres), therefore it is advisable to always purchase the screws and corresponding bits from the same supplier.
2-hole security fasteners are most commonly used in low to medium torque applications where moderate security resistance is required.
