Screwable spacer sleeve EB1550528175 M4 30mm Hexagonal

Screwable spacer sleeve EB1550528175 M4 30mm Hexagonal is a threaded standoff designed for M4 fasteners, offering a fixed 30 mm separation between assembled components. The hexagonal outer profile provides a secure grip for tightening with standard tools and ensures stable positioning in mechanical and electronic assemblies. The part is intended to create a reliable threaded connection while maintaining defined distance and alignment between panels, circuit boards or mounting brackets.

Advantages

The hexagonal outer shape allows easy tightening and prevents rotation during assembly, improving installation speed and repeatability. The screwable internal thread for M4 fasteners ensures consistent engagement and secure fastening. A 30 mm length provides a moderate standoff suitable for many common spacing requirements in enclosures, frames and brackets. The design supports reliable electrical isolation or mechanical separation when combined with appropriate materials.

Suitable for

• Mechanical assemblies requiring fixed spacing between parts
• Electronics housings and PCB mounting where a secure threaded spacer is needed
• Mounting brackets and panels that require distance and alignment control
• Prototyping and repair work involving M4 fasteners

Key specifications

• Thread size: M4 internal thread for screwable connection
• Length: 30 mm overall standoff length
• Outer profile: Hexagonal for wrench or socket engagement
• Function: Spacer sleeve / threaded standoff to maintain separation and allow fastening

How to use

Align the spacer sleeve between the two components to be separated and insert an M4 screw through the mating part into the threaded interior. Use the appropriate wrench or socket on the hexagonal outer profile to hold or rotate the sleeve as required while tightening the screw to the specified torque for your assembly. Ensure threads are clean and compatible with the screw material to avoid galling; if necessary, apply suitable thread lubricant or use a screw with compatible coating. Verify component alignment and secure fastening after installation.

Usage recommendations

For reliable long-term performance, select screws and mating materials that match the mechanical and environmental requirements of your application. When electrical isolation is required, confirm the spacer material and any surface treatments provide the needed insulation. During repeated assembly cycles, inspect threads and hex surfaces for wear and replace the spacer sleeve if deformation or thread damage is observed.
