RUKO STB-90°-M4-S-f Stainless Steel Standoff Bolt, M4 Female-Female, 90 mm

This RUKO STB-90°-M4-S-f standoff bolt offers a robust 90 mm spacing solution with M4 female threads on both ends, machined from stainless steel (V2A / 1.4305) for high corrosion resistance and electrical conductivity. Unlike typical standoffs, its 90° orientation and 6 mm body diameter make it ideal for PCB mounting and component spacing where a stable, conductive connection is required.

Highlights

• M4 female-female thread configuration, accepts standard M4 male screws
• 90 mm overall length, 6 mm body diameter for precise spacing
• Stainless steel (V2A / 1.4305) construction with natural silver finish
• Conductive and corrosion-resistant, suitable for electronics and mechanical fastening
• Operating temperature range -50°C to +250°C, RoHS compliant

In daily use

The STB-90°-M4-S-f provides a reliable standoff for PCBs, enclosures, and mechanical assemblies. Its internal threads are approximately 8 mm deep on each side, allowing secure fastening with M4 screws. The stainless steel material ensures long-term durability even in demanding environments, while the conductive properties support grounding applications.
