Description
BaerCoil UNF Thread Insert 1-12, 1.5xD is a precision internal fastener designed to renew and reinforce threaded holes, delivering durable, repeatable connections in demanding assemblies.
- Thread type: UNF 1-12 internal thread insert for secure, reliable engagement in threaded holes.
- Material: Austenitic stainless steel (AISI 304) with a tensile strength of at least 1400 N/mm2 for excellent corrosion and wear resistance.
- Cross-section: Rhombic profile produced by cold-form swaging, maximizing load distribution and space utilization inside the joint.
- Length: Dimensioned at 1.5xD to ensure proper thread engagement and withdrawal resistance.
- Durability advantages: Superior wear resistance, reduced thread abrasion, improved surface finish, and enhanced resistance to corrosion and heat compared with typical single-screw connections.
- Installation integrity: Designed for dependable installation in tapped holes, maintaining thread integrity under vibration and cyclic loads.
BaerCoil inserts restore and reinforce critical threads, extending service life and enabling repeated assemblies in mechanical, automotive, and industrial applications. With their robust stainless steel construction and optimized rhombic design, they deliver consistent performance where thread integrity is essential.
