Middle Atlantic HSK 100PC 10-32 SQDRIVE W/PIN

Product Overview

The Middle Atlantic HSK is a 100-piece pack of Guardian Series security rack screws featuring a patented square post drive design that discourages tampering with rack-mounted AV and IT equipment. These 10-32 by 3/4-inch screws come with factory-installed black nylon washers and self-guiding pilot points, making them a direct functional replacement for standard rack screws in installations where equipment security is a concern. The proprietary square post drive head cannot be removed with common tools, requiring the Guardian Series driver available from Middle Atlantic.

Product Description

Standard Phillips and hex rack screws can be removed by anyone with a basic tool kit, which is a concern in public-access AV installations such as classrooms, conference rooms, hotel AV closets, and entertainment venues. The Middle Atlantic HSK security screws address this by using a patented square post drive head that is unique to Middle Atlantic's Guardian Series hardware and cannot be operated with standard drivers. This provides a meaningful deterrent against unauthorized equipment removal or tampering without requiring physical locks or additional security hardware. The 10-32 by 3/4-inch thread specification is the standard rack screw format, so HSK screws install in the same positions as conventional rack hardware. Factory-installed black nylon washers protect equipment rack ear finishes from scratching, and the self-guiding pilot points help technicians start screws accurately in threaded rackrail holes without cross-threading. The black finish matches Middle Atlantic rack hardware for a consistent appearance. Sold in a 100-piece pack, providing enough screws for multiple rack builds or a complete security retrofit of an existing installation.
