Loctite Threadlocking

Threadlocking with Loctite®

Invented by Loctite Corporation, now Henkel Corporation, as a revolutionary method to lock and seal threaded fasteners, Loctite® liquid threadlockers have found wide acceptance in a range of applications - from delicate electronic components to heavy construction equipment. Loctite® threadlockers are available in varying viscosities and strengths for virtually any application, including exposure to extreme environments. Patented, revolutionary QuickStix semi-solid formulas offer added convenience and portability.

LOW STRENGTH

Loctite Variety Formulated for Notes
222MS THREADLOCKER Low Strength / Small Screw Purple. Ideal for fastener diameters of ¼" (6 mm) and smaller, long engagement length fasteners, and components requiring occasional adjustment. Apply to threaded parts before assembly. Controlled lubricity for accurate clamp loads. Parts can be disassembled with hand tools. Approved for use in or around food processing areas.

REMOVABLE STRENGTH

Loctite Variety Formulated for Notes
242 THREADLOCKER Medium Strength Removable strength, general purpose threadlocker adhesive well suited for fasteners between ¼" to ¾" diameter (6 to 20 mm). Applied to threaded components before assembly, Loctite® 242 Threadlocker has controlled lubricity for accurate clamp loads. Parts can be separated using hand tools. Approved for use in or around food processing areas.
243 THREADLOCKER Medium Strength / Oil Resistant A general purpose, medium strength threadlocker with improved oil tolerance. Suitable for ¼" to ¾" diameter (6 to 20 mm) fasteners.
246 THREADLOCKER Medium Strength / High Temperature This threadlocker resists oil and mild surface contamination at continuous temperatures to 450°F Suitable for ¼" to ¾" diameter (6 to 20 mm) fasteners.
248 THREADLOCKER Medium Strength / Semi-Solid Blue. New, patented semi-solid stick formula offers added convenience and portability. Like Loctite® 242, this threadlocker stick is well suited for ¼" to ¾" diameter (6 to 20 mm) fasteners and is removable with hand tools. The semi-solid formula also means it won't spill or leak.
2432 THREADLOCKER Medium Strength /Low Halogen / Low Sulfer This medium strength threadlocker was especially developed for use on sensitive metals, like titanium, used in the Nuclear Industry. Parts can be separated using hand tools.
2440 THREADLOCKER Primerless / Medium Strength This threadlocker is particularly fast curing, eliminating the need for primers. Performs well on all substrates. It develops usable strength within one hour. Parts can be separated using hand tools.

HIGH STRENGTH

Loctite Variety Formulated for Notes
262 THREADLOCKER Medium to High Strength A permanent, high strength product that is applied to fasteners up to ¾" (20 mm) in diameter before assembly. High lubrication for easy assembly. Excellent for preventing rust and corrosion in extreme chemical/environmental conditions. Localized heat and hand tools are required to separate parts. Solvents will not weaken the adhesives bond. Approved for use in or around food processing areas.
266 THREADLOCKER High Strength / High Temperature Fast fixturing threadlocker resists oil and mild surface contamination at temperatures to 450°F. Locks fasteners up to ¾" (20 mm) in diameter.
QUICKSTIX 268 THREADLOCKER High Strength / Semi-Solid Red. Revolutionary semi-solid stick formula is high strength and best suited for fasteners up to ¾" (20 mm). Semi- solid formula offers added convenience and portability. Localized heat and hand tools are required to separate parts.
271 THREADLOCKER High Strength A high strength, low viscosity threadlocker for fasteners up to 1" (20 mm) in diameter.
272 THREADLOCKER High Strength / High Temperature Withstands temperatures to 450°F. Provides a fast cure on most surfaces, including "as received" fasteners. Recommends for bolts up to 1½" (36 mm) in diameter. Heat and hand tools are required for disassembly.
277 THREADLOCKER High Strength Locks fasteners up to 1½" (36 mm). Protects threads from rust and corrosion. Removable with heat and hand tools.
2760 THREADLOCKER Primerless / High Strength This threadlocker is particularly fast curing, eliminating the need for primers. It develops usable strength within one hour. Particularly suitable for heavy duty applications where resistance to heavy shock, vibration and stress levels is required.

WICKING

Loctite Variety Formulated for Notes
220 THREADLOCKER Medium Strength Blue. A low viscosity threadlocking adhesive that allows the product to wick along the threads of preassembled fasteners. Perfect for fasteners up to ¼" diameter (6 mm).
290 THREADLOCKER Medium Strength Green. A low viscosity, medium strength threadlocker for pre-assembled bolts up to ½" (12 mm) to secure them in place. Penetrates threads by capillary action. Seals porosities in welds and metal parts. Secures set screws and other assemblies after setting are completed. Seals welds and porous metal parts. Protects threads from rust and corrosion. Localized heating and hand tools are needed for disassembly.
294 THREADLOCKER Wicking Grade / High Temperature Ideally suited for pre-assembled fasteners. Performs well on oily fasteners.

PLASTIC

Loctite Variety Formulated for Notes
425 ASSURE INSTANT ADHESIVE Surface Curing Threadlocker Low strength, fast curing threadlocker for plastic fasteners. Can be used as a tamper-proofing agent for the head of screws. Can be applied before or after assembly.

GEL

Loctite Variety Notes
TIGHT MULTI-PURPOSE ANAEROBIC GEL This products seals, locks, and retains. It seals against most liquids and gases and works well on coarse threads, large gaps, and all overhead applications.

PRIMER

Loctite Variety Notes
7649 PRIMER N Decreases the set-up time of Loctite threadlockers and increases breakaway torque on most fastener surfaces. Allows application of threadlockers in cold weather. Contains no ozone-depleting compounds.
