High-strength threadlocking for large fasteners
Loctite 268 is a red anaerobic threadlocker supplied as a 19 g solid stick. It secures threaded assemblies from 1/4 in to 3/4 in diameter on brass, bronze, copper, iron, manganese, Monel, nickel and steel. The no-drip formula prevents migration during application.
Cures anaerobically with no-drip application
The compound cures in the absence of air between engaged threads. Working time is 5 min before the bond begins to set. Breakaway torque reaches 90 in-lb once fully cured. Compatible primer Loctite 7649 can accelerate cure on inactive surfaces if required.
Maximum thread diameter 3/4 in
This stick is formulated for fasteners up to 3/4 in diameter. Larger bolts or studs fall outside the specified range and need a different grade. Buyers who need to lock threads above that size should select an alternative product.

Questions about this item
How do I install the Loctite 268 stick on a 3/4 in bolt, and what step is often missed?
Apply the stick directly to clean threads up to 3/4 in diameter, assemble within 5 minutes working time, and allow anaerobic cure; the step often missed is using Loctite 7649 primer on inactive metals for reliable bonding.
What maintenance or replacement will the Loctite 268 threadlocker need after curing?
The cured threadlocker is permanent; no maintenance is required, but disassembly requires heat and hand tools to reach 90 in-lb breakaway torque, after which fresh Loctite 268 must be reapplied for reassembly.
What limit appears first when the Loctite 268 stick is used continuously on large fasteners?
The 19 g stick yields roughly 0.67 oz of material, so sustained use on 3/4 in threads depletes the supply quickly, making stick replacement the first practical limit.
