Plastic mounting discs SCHROFF NTS set 100 pieces, MPN 21100-016

Set of 100 SCHROFF NTS plastic mounting discs designed for secure insulation and spacing of components inside electronic enclosures and rack systems. These lightweight, non-conductive discs are intended to prevent electrical contact between hardware elements and to protect circuit boards, panels and fasteners from mechanical abrasion and short circuits. The set is supplied in a single package of 100 pieces for repetitive assembly tasks and maintenance operations.

Advantages

Plastic mounting discs provide electrical insulation and reduce the risk of short circuits by creating a reliable air gap between conductive parts. Their uniform shape and dimensions make positioning and installation straightforward, while the material resists typical workshop contaminants and provides stable performance under normal industrial conditions. A set of 100 reduces the need to repeatedly restock small quantities for prototype builds or repair work.

Suitable for

• Mounting and insulating printed circuit boards in enclosures and racks
• Separating panels, standoffs and fasteners to prevent metal-to-metal contact
• Prototype assembly, small-series production and field maintenance
• Repair work where lightweight, non-conductive spacers are required

Key specifications

• Material: non-conductive plastic
• Quantity: 100 pieces per set
• Form: round mounting discs
• Function: insulating spacer and protective washer
• Typical use environment: electronic enclosures and rack systems

How to use

Select the appropriate disc size and position the disc between the component and the mounting surface so that contact points are insulated. Place the disc over the screw, stud or standoff and tighten the fastener to the required torque while ensuring the disc remains correctly seated. Use multiple discs as required to achieve the intended spacing or insulation thickness. Verify that the assembled parts are stable and that the disc does not deform under load in the specific application.

Usage recommendations

Store discs in a dry environment away from direct sunlight and high temperatures to avoid material aging. For applications with specific temperature, chemical or mechanical stress, confirm material compatibility prior to installation and replace any deformed or cracked discs. When electrical insulation under higher voltages is required, choose spacers rated for the necessary dielectric strength.
