Break-Away Bolts & Pre-Cast Inserts

Tanner manufactures and distributes round and flat head Break-Away bolts in size range #10-24 through 3/4". Ideal for high security applications where removability is not required. Tamperresistant head configuration will ward off the most determined attacks. Break-Away bolts are installed with standard wrenches to attach fixtures to internally threaded materials or inserts.

Parts are made-to-order based on customer specifications, including dimensions, material, finishes, and torque tightening requirements. Certain sizes are kept in stock. Please contact a Tanner sales representative for further details at 800-456-2658 or request a quote here.

Break-Away Nuts a Non-Removable Security Solution

Pre-Cast Concrete Inserts

Concrete Inserts are designed to use in precast, prestressed or poured-in-place concrete. The zinc alloy body (Zamak 5) provides for maximum corrosion resistance and mar-free installations. The thick, solid anchor walls yield rock solid strength and durability. The die-cast threads offer superior strength compared to tap & die threads, and the wide base grips the concrete for superior anchor strength.

Applications:

Prison Cells
Railings
Burial Vaults
Machinery
Utility Poles
Benches
