Quarter turn fastener lock SCHROFF Model 21101848, pack of 100 pieces

Quarter turn fastener lock SCHROFF Model 21101848, pack of 100 pieces provides a set of metal quarter-turn fasteners intended for panel and enclosure fastening in equipment cabinets, rack panels and electronic housings. Supplied as a bulk pack of 100, the fasteners enable quick engagement and disengagement with a 90° turn, offering consistent mechanical retention and repeatable closure without the need for additional tools in many installations.

Advantages

These quarter-turn fasteners are designed for reliable, repeatable operation and compact installation footprint. Their quarter-turn mechanism reduces time required for access compared with multiple-screw solutions, and the consistent detent action supports predictable closing torque. Supplied in a pack of 100, the set is suited to production, maintenance and repair work where multiple identical fasteners are required. Materials and finishing provide resistance to ordinary workshop conditions and ensure secure retention of panels during transport or operation.

Suitable for

• Securing removable panels on equipment cabinets and server racks
• Fastening access doors and covers on electronic enclosures
• Production assembly and maintenance in industrial electronics
• Retrofitting or replacing worn quarter-turn fasteners in racks and cabinets

Key specifications

• Operation type: quarter-turn (90°)
• Pack quantity: 100 pieces
• Mounting: panel-mounted fastening suitable for thin panels and enclosure walls
• Retention: positive detent action for repeatable closure
• Typical materials and finish: metal construction with corrosion-resistant surface treatment

How to use

Install each fastener into the pre-cut hole in the panel or enclosure according to the panel thickness and mounting requirements. Engage the mating component and rotate the fastener by 90° to secure the panel; reverse the turn to release. Ensure that the fastener aligns correctly with the mating catch or keeper before applying torque. For repeated service access, verify that the detent action provides the necessary holding force and that the panel sits flush after closure.

Usage recommendations

Use with panels and enclosures that match the specified panel thickness range and hole diameter for the fastener. Avoid excessive torque beyond the detent specification to prevent deformation. For environments requiring enhanced corrosion protection or vibration resistance, consider additional washers or locking features as appropriate for the installation.
