Description

Loctite 271 Acrylic Anaerobic Threadlocker Red 50ml

  • Strength : High
  • Viscosity : 400 - 600 mPa.s (cP) Brookfield
  • Key Substrates : Metal: Brass, Metal: Steel, Metal: Steel - Stainless Steel
  • Color : Red
  • Curing Type : Anaerobic
  • Application : Threadlocking
LOCTITE® 271 is a red, low viscosity, methacrylate-based threadlocking adhesive with high strength. With steel fixture time of 10 min, brass 5 min and stainless steel 15 min. Can tolerate slight contaminations of industrial oils. Suitable for all metal fasteners. Breakaway torque on M10 bolts of 26 Nm. Fluoresces under UV light.
  • Low viscosity
  • Fluoresces to allow quality control and inspection
  • Prevents unwanted movement, loosening, leaks and corrosion
  • Resists vibration
  • High strength
  • Seals threads - allows through-hole tapping
LOCTITE®
271™ is designed for the permanent locking and
sealing of threaded fasteners. The product cures when
confined in the absence of air between close fitting metal
surfaces and prevents loosening and leakage from shock and
vibration. Typical applications include the locking and sealing
of large bolts and studs (up to M25 ).

LOCTITE®
271™ is tested to the lot requirements of Military
Specification Mil-S-46163A. Note: This is a regional approval.
Please contact your local Technical Service Center for more

TYPICAL CURING PERFORMANCE

Cure Speed vs. Substrate

The rate of cure will depend on the substrate used.The graph
below shows the breakaway strength developed with time on
M10 steel nuts and bolts compared to different materials and
tested according to ISO 10964.
Cure Speed vs. Temperature

The rate of cure will depend on the temperature. The graph
below shows the breakaway strength developed with time at
different temperatures on M10 steel nuts and bolts and tested
according to ISO 10964.
Cure Speed vs. Activator

Where cure speed is unacceptably long, or large gaps are
present, applying activator to the surface will improve cure
speed. The graph below shows the breakaway strength
developed with time on M10 zinc dichromate steel nuts and
bolts using Activator 7471™ and 7649™ and tested according
to ISO 10964.
GENERAL INFORMATION

This product is not recommended for use in pure oxygen
and/or oxygen rich systems and should not be selected as
a sealant for chlorine or other strong oxidizing materials
For safe handling information on this product, consult the
Material Safety Data Sheet (MSDS).
Where aqueous washing systems are used to clean the
surfaces before bonding, it is important to check for
compatibility of the washing solution with the adhesive. In
some cases these aqueous washes can affect the cure and
performance of the adhesive.
This product is not normally recommended for use on plastics
(particularly thermoplastic materials where stress cracking of
the plastic could result). Users are recommended to confirm
compatibility of the product with such substrates.
Directions for use:

For Assembly


  1. For best results, clean all surfaces (external and internal)
    with a LOCTITE®
    cleaning solvent and allow to dry.
  2. If the material is an inactive metal or the cure speed is
    too slow, spray all threads with Activator 7471™ or
    7649™ and allow to dry.
  3. Shake the product thoroughly before use.
  4. To prevent the product from clogging in the nozzle, do
    not allow the tip to touch metal surfaces during
    application.
  5. For Thru Holes, apply several drops of the product onto
    the bolt at the nut engagement area.
  6. For Blind Holes, apply several drops of the product
    down the internal threads to the bottom of the hole.
  7. For Sealing Applications, apply a 360° bead of product
    to the leading threads of the male fitting, leaving the first
    thread free. Force the material into the threads to
    thouroughly fill the voids. For bigger threads and voids,
    adjust product amount accordingly and apply a 360°
    bead of product on the female threads also.
  8. Assemble and tighten as required.

For Disassembly


  1. Apply localized heat to nut or bolt to approximately
    250 °C. Disassemble while hot.

For Cleanup


  1. Cured product can be removed with a combination of
    soaking in a Loctite solvent and mechanical abrasion
    such as a wire brush.
