Carbon Steel Blind-Threaded Standoffs BSO
Product Overview
Blind-Threaded Standoffs BSO are crucial components in the world of mechanical assemblies, especially where secure and reliable spacing is needed in sheet metal fabrication. Designed for mounting applications, these standoffs are installed into blind holes to provide permanently mounted, load-bearing threads. They are particularly suited for applications involving printed circuit boards, panels, and other sheet materials where back access isn’t available.
Engineered from carbon steel for high strength and durability, Blind-Threaded Standoffs BSO offer excellent performance for automated and manual assembly processes. Their blind-threaded feature ensures safety and structural integrity, especially in electrical and electronic enclosures.
These standoffs are also known for their flush installation and secure grip, making them a top pick for OEMs and manufacturers looking for reliable, high-performance fasteners.

Material Details & Manufacturing Process
The Blind-Threaded Standoffs BSO are manufactured from high-grade carbon steel, a material chosen for its strength, cost-effectiveness, and machinability. Every piece goes through a precise cold-forming process to ensure consistent dimensions and structural performance.
After forming, standoffs are heat-treated to achieve the required mechanical properties and then surface-coated, typically with zinc plating, to provide corrosion resistance. This finish meets RoHS environmental standards and ensures long-lasting durability in industrial conditions.
Production is carried out under strict quality controls, employing CNC machining, threading, deburring, and passivation where necessary. Each batch is thoroughly tested for dimensional precision and mechanical strength.
Common Applications and Industries Served
These Blind-Threaded Standoffs BSO are widely used across various industries, including:
- Consumer electronics and PCB assembly
- Telecommunications enclosures
- Machinery and control panels
- Aerospace and automotive electronics
- Medical device manufacturing
- Renewable energy systems (inverters, battery enclosures)
They are especially beneficial when reverse side accessibility is limited, making press-in installation ideal for dense electronic layouts.
