BaerCoil UNF thread inserts are precision-engineered fasteners designed to reinforce and repair threaded holes in high-stress assemblies. Crafted from austenitic stainless steel (AISI 304) with a tensile strength of at least 1400 N/mm2, this insert is sized for a 1-1/2" major diameter and 12 threads per inch, with an overall length of 1.5 times the diameter (approximately 2.25 inches).

• Thread Size: UNF, 1-1/2" major diameter, 12 TPI
• Length: 1.5 × D (about 2.25" / 57 mm)
• Material: AISI 304 stainless steel (austenitic chromium-nickel)
• Strength: Tensile strength ≥ 1400 N/mm² for durable performance
• Cross-Section & Forming: Rhombic cross-section achieved by cold-form swaging for a precise fit and maximum space utilization
• Performance: Superior wear resistance, better surface finish, and enhanced corrosion and heat resistance compared with standard single-thread connections

BaerCoil inserts help restore damaged threads and reinforce joints that experience vibration, wear, or high loads. The stainless-steel composition resists corrosion and heat, extending the life of critical fastenings while maintaining reliable engagement with mating screws. The rhombic, swaged design ensures a consistent, secure bite in the hole, delivering lasting torque stability and smoother operation in demanding applications.
