Medium-strength threadlocking stick for metal

Loctite 248 is a solid, no-drip anaerobic adhesive supplied in a 0.67 oz stick. It locks and seals threaded assemblies on brass, bronze, copper, iron, manganese, Monel, nickel and steel up to a 3/4 inch maximum diameter. The blue colour indicates medium breakaway strength for removable joints.

Anaerobic cure with five-minute working time

The compound begins to set in the absence of air once parts are assembled, giving a five-minute working window for alignment. Fully cured joints deliver a breakaway torque of 200 in-lb while resisting vibration and leakage. Solid stick format eliminates drips and mess during application.

Primer 7649 compatibility for faster cure

For inactive metals or larger gaps, Loctite 7649 primer accelerates the anaerobic reaction and ensures full strength development. The product carries a California Proposition 65 warning for reproductive-harm chemicals. Restricted from sale in certain states.

Questions about this item

How do I apply the stick threadlocker to a 3/4 in bolt and what step is often missed?

Twist the stick to expose the solid formula, coat the male threads evenly, then assemble within the 5 min working time — the step most often missed is waiting for full anaerobic cure before loading the joint.

When will the 0.67 oz stick need replacement?

Replace the stick when the solid material is used up or if it hardens inside the container; no scheduled maintenance is required for the cured threadlock itself.

What is the first limit reached under sustained vibration and heat?

The joint will hold until breakaway torque exceeds 200 in-lb; beyond that the medium-strength bond yields and the fastener can loosen.
