Recoil® 13524D Tanged Screw-Locking Coil Threaded Insert, #2-56 UNC, 2D/0.172 Inch Length, DRY-FILME LUBED

Screw-locking inserts provide an exclusive, resilient internal locking thread that grips the bolt and prevents it from loosening under vibration or impact. Locking action is achieved by one or more of the coils of the insert having a series of straight segments, or chords. When the bolt enters this grip coil, these chordal segments flex outward creating pressure on the bolt. This pressure is exerted between the flanks of the bolt thread thus utilizing the maximum contact area and minimizing the unit pressure. Screw-lock inserts permit repeated assembly and disassembly yet will not relax their grip on the screw even in tough metals such as cast iron, alloy steel, titanium, etc.

• Used for mildly corrosive or high temperature applications, dry film lubricants comprise suspensions of small particles of solid lubricants such as molybdenum disulphide (MoS2) or PTFE, in organic or inorganic binders
• They are applied as a thin film (5µm - 20µm) to grease-free metal surfaces
• Through careful selection of appropriate additives and solvents, specific lubricants may be formulated to suit most industrial applications to service temperatures around 315°C (600°F)
• Special high temperature lubricant coatings are available for use up to 425°C (800°F)
• Recoil inserts may be coated with dry film lubricant in either the non-finished (passivated) condition or after cadmium plating treatment for maximum corrosion protection
