Description
Overview:
T71 (Replaces Loctite 271) Retaining Compound is a genuine Lockfast red, high‐strength threadlocker supplied in a 50 ml bottle. It is a low‐viscosity anaerobic adhesive designed to permanently secure and seal large threaded studs and bolts, typically over M25, in demanding service. With a viscosity of 400-600 mPa·s (cP), it flows cleanly into thread roots during assembly to maximise surface contact and joint integrity. The compound operates reliably from -54°C to 150°C and is UV positive to aid inspection under UV light, helping confirm coverage on critical fasteners. T71 is well suited to construction and garden machinery, including heavy plant, compactors, and professional lawn and grounds equipment, where vibration, shock, and high loads demand dependable, long‐term retention.
Key Features:
- Genuine Lockfast part for assured quality and consistency
- High‐strength red threadlocker for permanent retention of large fasteners (M25 and above)
- Replaces Loctite 271 in equivalent applications
- Low viscosity 400-600 mPa·s (cP) for easy dispensing and full thread wetting
- Breakaway torque: 17-40 N·m; prevail torque: 23-40 N·m (typical on standard test assemblies)
- Wide service temperature range: -54°C to 150°C for all‐season use
- Rapid fixture for quick handling; full cure follows standard anaerobic cure profile
- UV positive for simple in‐process inspection and quality control
- Helps prevent loosening from vibration and thermal cycling
- Seals threads against leakage and corrosion, supporting long service life
- Suitable for construction plant, agricultural and garden machinery maintenance and repair
Typical Applications:
Permanent locking of large studs and bolts on gearboxes, engine housings, frame and chassis fixings, couplings, pulley and drive assemblies, attachments, and other high‐load joints on construction equipment and professional garden machinery. Ideal for vibration‐prone and safety‐critical fasteners where controlled disassembly is not expected. Use on clean, dry, oil‐free metal threads during assembly to improve joint reliability and reduce rework in harsh operating environments.
