Thomas & Betts Ty-Rap TY523MX 4" 18 lb Nylon Cable Ties

Thomas & Betts Ty-Rap TY523MX is a 4-inch, 18 lb. black nylon cable tie with a stainless steel locking device, designed for low-profile, weather-resistant bundling.

These Ty-Rap cable ties combine a smooth, notchless nylon body with a corrosion-resistant stainless steel locking insert to deliver precise clamping without stress concentration points. The 6.6 weather-resistant nylon formulation and ultraviolet-stable black finish make the TY523MX suitable for indoor and outdoor installations, while the low-profile head and rounded edges help prevent snags and protect wire insulation during routing and through bulkheads. Packaged as 100 ties, they meet the military standard MS3367-4 for consistent size and performance.

How does the stainless steel locking device improve performance?

The stainless steel insert provides a strong, reliable bite on the strap while resisting corrosion in humid or outdoor environments. Because the lock is metal, it maintains consistent clamping force and resists deformation from repeated tensioning.

• Non-magnetic stainless steel resists rust and maintains strength
• Delivers repeatable tightness for secure bundles
• Reduces chance of slippage compared with plastic-only locks

Why choose a notchless, low-profile Ty-Rap over notched ties?

The smooth, notchless body allows infinite locking positions for precise diameter control and distributes stress more evenly along the strap. A low-profile head lowers the risk of catching on equipment and makes passing ties through tight bulkheads easier.

• No notches = exact tensioning at any point along the strap
• Smooth body reduces stress concentration and improves tensile performance
• Low-profile head prevents snags and eases installation in confined spaces

What environmental and physical specs should I expect?

These ties are made from Nylon 6.6 with weather-resistant additives and a UL 94 V-2 flammability rating. They are rated for temperatures between -40°F and 185°F and provide reliable performance across a wide range of common industrial and outdoor conditions.

• Material: Nylon 6.6 (weather resistant)
• Temperature range: -40°F to 185°F
• Width: 0.093 inches; tensile hold ~18 lb.

How do Ty-Rap ties protect cables and insulation?

Rounded edges and a ribbed/stippled body reduce abrasion and slipping once tightened. The no-slip tail gives a better grip for tensioning so installers can apply the right amount of force without cutting into insulation.

• Rounded edges minimize cut-through risk on cable jackets
• Ribbed/stippled surface improves grip on bundled cables
• No-slip tail simplifies manual tensioning without damaging components

Who is this for: The Thomas & Betts Ty-Rap TY523MX ties are suited for electricians, telecom and network installers, marine and aerospace maintenance, and facilities teams that need compact, corrosion-resistant bundling solutions. They work well for temporary or permanent cable management where precise tensioning, UV resistance, and a low-profile finish are important. If you require consistent, military-standard 4-inch ties in a reliable 100-count pack for fieldwork or shop inventories, these are a practical choice.
