LOCTITE 271 is a high-strength red anaerobic threadlocker for permanent locking of studs, bolts and press-fit assemblies — Multi Trade Combines stocks it in Guwahati, price on request.
LOCTITE 271 is a high-viscosity, anaerobic, red-coloured threadlocker from the Henkel Loctite range. Once applied between mating threads and exposed to the absence of air, it cures into a thermoset plastic that prevents loosening due to vibration, shock, and thermal cycling. The 271 designation marks it as a high-strength permanent formula — the kind you reach for when a fastener must never back out in service.
Industrial workshops across Northeast India deal with continuous vibration: mining equipment in Meghalaya, tea-garden machinery in upper Assam, earthmoving plant on PWD road contracts in Nagaland and Arunachal Pradesh. Standard lock-washers and prevailing-torque nuts lose grip over thousands of operating hours. LOCTITE 271 fills the thread valleys, displaces the entrapped air, and cures into a bond that outlasts the surrounding metal in most service environments.
It is particularly valued for stud anchoring — gearbox studs, pump-bracket bolts, engine-mount hardware — where the assembly is meant to be permanent and any loosening risks equipment damage or injury. Automotive garage technicians use it for wheel-hub studs and diff-cover hardware. Fabricators applying it to press-fit retaining compounds find it doubles up as the sealing element, preventing rust creep into the joint.
Multi Trade Combines, authorised Loctite distributor in Guwahati since 1993, stocks 271 in the standard 10 ml and 50 ml bottles. Pair it with Loctite 7471 Primer/Activator for passive metals like stainless or zinc-plated surfaces.

LOCTITE 271 is a high-strength red threadlocker designed for permanent fastener locking — removal requires significant heat (250 °C+). LOCTITE 243 is a medium-strength blue formula that allows disassembly with standard hand tools during maintenance, making it suitable for bolts that need periodic servicing.
Yes. LOCTITE 271 performs well on passive metals including stainless steel. In humid or tropical environments like Assam and Northeast India, it actually outperforms standard mechanical locking methods by sealing the thread interface against moisture ingress and corrosion. An activator is recommended on very smooth or inactive surfaces.
