Professional Applications & Engineering Value

This hollow threaded stud delivers critical engineering solutions where both structural integrity and internal routing capabilities are required. The 18-8 Stainless Steel material provides excellent resistance to oxidation and chemical exposure, making it suitable for industrial machinery, electrical enclosures, and fluid systems. The 1/4"-20 UNC coarse threads and Class 2A thread fit ensure rapid assembly with consistent torque performance, reducing installation time while maintaining joint security. The 1/8" hollow center allows for integration of cables, lubrication lines, or sensors, eliminating the need for separate conduits. Right-hand threading on both ends facilitates symmetrical load distribution, ideal for precision threaded fastener applications in manufacturing and automation.

Specification Summary & Compliance

Manufactured to standard UNC coarse thread specifications with Class 2A external thread fit for consistent dimensional accuracy. Complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental and safety adherence. Threading is right-hand direction with 1 1/2" length on both ends, supporting ASME/ANSI aligned assembly requirements.
