Sleeve/Insert SCHROFF for M6 threaded fasteners, plastic black, pack of 100

Plastic sleeve/insert by SCHROFF designed for use with M6 threaded fasteners. Supplied in a pack of 100 black sleeves, this non-conductive insert provides insulation and spacing for panel mounting, electronic enclosures and mechanical assemblies. The part is intended to create a defined separation between metal components, reduce direct metal-to-metal contact, and offer light vibration damping where M6 screws and bolts are used.

Advantages

The black plastic sleeve delivers electrical insulation and prevents short circuits between fasteners and surrounding conductive surfaces. Its molded shape ensures consistent spacing and alignment for M6 threaded fasteners, simplifying installation and repeatability in production or service. The plastic material offers corrosion resistance compared with bare metal spacers and contributes to reduced acoustic transmission of vibrations in assemblies.

Suitable for

• Panel mounting and fastening of control or instrument panels
• Electrical and electronic enclosures requiring non-conductive separation
• Mechanical assemblies where precise spacing for M6 screws is needed
• Applications needing light vibration damping or isolation of fasteners

Key specifications

• Compatible thread size: M6
• Material: black plastic (non-conductive)
• Package quantity: 100 pieces
• Function: insulation, spacing and light vibration damping
• Typical applications: panel mounting, enclosures, mechanical fixtures

How to use

Insert the sleeve into the mounting hole or position it over the M6 fastener before inserting the screw or bolt. Ensure the sleeve is seated flush and aligned with the hole to maintain intended spacing and insulation. Tighten the M6 fastener to the required torque for your assembly, taking care not to deform the sleeve with excessive force. For removal, back out the fastener and withdraw the sleeve; inspect for wear or deformation before reuse.

Usage recommendations

Use these sleeves where electrical insulation between fasteners and conductive parts is required and in assemblies where a consistent spacer for M6 screws improves fit and function. Avoid exposure to strong solvents or temperatures outside the material's rated range; verify compatibility with your operating environment before extended use.
