Advanced Thumbscrew Hold-Downs

Avionics equipment mounting structures for all types of aircraft. OEM equipment on commercial, military and rotorcraft as well as specialized configurations for unique applications.

These hold-downs have a secure ratcheting locking mechanism that meets the performance standards of MS14108, MIL-F-85371, are RoHS compliant and are the industry standard for a thumbscrew hold-down restraint of avionics equipment.

The adaptable design allows for creating a tight seal between the surface it is assembled onto, or the other surfaces it is in contact with. A variety of lengths are available per request.

Designed as an upgrade to the NAS1637 Adjustable Keeper with Mounting Provisions, this product interfaces with the NAS1637 latch to retain Line Replaceable Units (LRUs) into ARINC 404-style trays.

Our Male/Female Threaded Hex Stand-offs are ideal for clamping wire bundles or tubes away from a bulkhead or to route through various structural installations.

Amphenol CIT offers a variety of positive-pressure solutions to capture contaminants before they ever enter the cooling system or equipment.

These systems significantly reduce the ingression of cooling air contaminants entering the equipment with top-to-bottom cooling flows.

We have developed an easy-to-integrate module that incorporates a high-sensitivity pneumatic sensor and aircraft-grade relay into a single package.

We offer several types of installation force-limiting hold-downs with extraction features to protect the blind-mate connectors interfacing your equipment and ease maintenance, removal, and replacement.
