Product Name
Permabond LM113 Anaerobic Threadlocker medium viscosity
Brief Description
Permabond LM113 is a low-strength anaerobic threadlocker adhesive with medium viscosity. It is a fast-curing liquid designed for locking small threaded fasteners, such as screws, bolts, and hydraulic fittings. This product effectively prevents vibration loosening and allows for easy disassembly using standard hand tools. Additionally, it provides corrosion protection and thread lubrication, contributing to easier assembly and enhanced durability.
Popular Applications & Uses
- Locking small threaded fasteners (screws, bolts).- Securing hydraulic fittings.- Preventing vibration loosening in mechanical assemblies.- Applications requiring easy disassembly with hand tools for maintenance or repair.- Providing corrosion protection for fasteners.- Lubricating threads for smoother assembly.- Securing components in electronics and delicate assemblies where low strength is preferred.
Industries that Commonly Use It
- Aerospace/Defense- Automotive Service/Repair- General Manufacturing- Government & Military- Industrial Supply- Marine- Metal Fabrication- Engineering Services- Distributers & Resellers
Special and Unique Features
- Low-strength formulation, ideal for fasteners that require removal with hand tools.- Thixotropic viscosity prevents run-off, ensuring precise application and controlled bonding, especially on small parts.- Fast curing at room temperature, achieving handling strength in approximately 15 minutes and full cure within 24 hours.- Meets military specifications MIL-SPEC MIL-S-46163A Type II, Grade M (Group 03, Class 1, Grade 1) and ASTM D5363 AN 0311, ensuring compliance for military, aerospace, and industrial applications.- Provides controlled off-torque, which is beneficial for consistent disassembly.- 100% Solids and Solvent-Free, making it an environmentally friendly option for industrial use.
Key Properties
- Chemical composition: Methacrylate esters.- Appearance/Color: Purple.- Viscosity @ 25°C: 1,200 mPa.s (cP) (thixotropic).- Gap Fill: 0.15 mm (0.006 in).- Maximum Thread Size: M20 (¾”).- Handling Strength: Approximately 15 minutes at 23°C (73°F).- Full Cure Time: 24 hours.- Temperature Range: -55°C to 150°C (-65°F to 300°F).- Torque Strength (M10 Steel, ISO 10964): Break: 9 N·m (80 in.lb); Prevail: 5 N·m (40 in.lb).- Shear Strength (Steel Collar & Pin, ISO 10123): 5 MPa (750 psi).- Specific Gravity (uncured): 1.1.
Surface Compatibility
- Steel- Cadmium- Zinc- Other plated fasteners- Most metals, including anodized aluminum, stainless steel, brass, oily, and “as received” finishes.- Can be used on inactive or passive surfaces, though cure speed may be reduced; activators like Permabond A905 or ASC10 can be used to accelerate cure.

Comparison Note
Permabond LM113 stands out as a low-strength anaerobic threadlocker, specifically formulated for applications where easy disassembly with hand tools is a primary requirement. This characteristic distinguishes it from medium-strength threadlockers (typically blue), which offer a stronger hold but are still removable with hand tools, and high-strength threadlockers (often red), which are designed for permanent assemblies and usually require heat for removal. Its thixotropic nature is a key advantage, preventing the adhesive from running off the application area, making it particularly suitable for small or precision parts.
