PEM® BSO Blind Threaded Standoffs
Permanent Threaded Mounting with a Flush, Closed-Paneled Design
PEM® BSO Blind Threaded Standoffs provide a strong, permanent mounting solution for applications where components must be spaced or mounted while keeping the opposite side of the panel completely closed.
Using proven PEM® self-clinching technology, BSO standoffs install into properly sized round mounting holes with a squeezing force and become permanently retained in thin sheet. Their blind-threaded design keeps the outer sheet surface flush and closed, making them ideal for electronic enclosures, equipment housings, control systems, and other assemblies where exposed mounting hardware or through-holes are undesirable.

Discover the Features + Benefits | PEM® BSO Blind Threaded Standoffs
- Blind Threaded Design: The closed-end internal thread keeps the outer sheet surface completely closed, helping create a cleaner enclosure design while preventing the mating screw from extending through the opposite side.
- Flush Exterior Surface: Installation leaves the reverse side of the sheet flush, eliminating protruding hardware and helping maintain a clean exterior appearance.
- Proven Self-Clinching Technology: Installs into a properly sized round mounting hole using a squeezing force. Once installed, the standoff becomes permanently mounted to the sheet.
- Maintain a Clean Exterior: The blind design allows engineers to create an internal threaded attachment point without creating an exposed hole or protruding fastener on the exterior surface.
- Protect Internal Components: A closed mounting point can help separate the interior assembly from the external environment compared with an open through-hole design.
- Simplify Component Mounting: The permanently installed threaded standoff eliminates the need to handle loose nuts, spacers, and washers during final assembly.
PEM® BSO Blind Threaded Standoffs are well suited for applications requiring permanent component spacing and a closed exterior surface, including:
- Electronic enclosures
- Printed circuit board assemblies
- Server and networking equipment
- Data center hardware
- Telecommunications equipment
