Tamper Resistant Spanner Snake Eye Bits

Tamper Proof Security Bits

Spanner bits are used in a hex screw driver or wrench to insert or remove tamper proof security screws. These bits are made from black alloy steel. Available sizes include: #4, #6, #8, #10, #12 and 1/4" (#14)

These bits are used with spanner security screws. Spanner Screws are commonly referred to as "Snake Eye" because of the two dot drive system.

Security screws are used primarily in public areas, securing materials from being tampered with. These include: gutters, license plates, grills in jails, schools, boats, cars, food prep / processing areas, and most commonly in public restroom stalls or partitions.
