Precision Brass Threaded Inserts

Precision brass threaded inserts represent a cornerstone of reliable fastening technology across demanding industrial applications. Our manufacturing process integrates tight tolerances, superior material purity, and consistent thread geometry to deliver components that outperform standard inserts in vibration resistance and pull-out strength. Drawing on two decades of engineering insight, we produce inserts from high-grade brass alloys such as C36000 and C37700, ensuring excellent machinability, corrosion resistance, and electrical conductivity. These attributes make them particularly well-suited for electronics housings, automotive sensor mounts, and pneumatic valve assemblies. Related capabilities include Brass CNC Turned Components for precision shafts and connectors, Copper Alloy Machined Fittings for fluid and gas systems, Custom Copper CNC Turned Parts for bespoke thermal and electrical interfaces, and Brass Machining Hardware Fittings covering a broad range of structural connecting elements. The threaded insert line is manufactured to accommodate unified, metric, and custom thread forms, with knurled, straight, or hex bodies for optimal anchoring in thermoplastics, thermosets, and soft metals like aluminum or magnesium.
Precision Brass Threaded Inserts are engineered with a focus on installation repeatability and long-term joint integrity. The table below details core dimensional and mechanical parameters for our standard insert families, all values validated through CMM inspection and destructive pull-out testing per ASTM D6117. The listed performance figures assume insertion into properly sized pilot holes in common engineering polymers; for metal substrates, we recommend consulting our engineering team to adjust hole diameters and engagement lengths. Beyond the standard range, we offer custom lengths, flange configurations, and under-head geometries to match specific assembly constraints. Thread quality conforms to ASME B1.1 for unified threads and ISO 965 for metric threads, with optional class 3B or 4H fits for high-precision applications. Surface finishes include natural brass, nickel plating, and tin plating for enhanced solderability or corrosion protection. All inserts undergo 100% optical sorting for dimensional conformity and random lot sampling for hardness and tensile verification. The combination of precision machining, controlled knurl depth, and lead-in chamfer reduces installation torque while maximizing resistance to rotational and axial loads in both through-hole and blind-hole designs.
