Gould Fasteners, a leading Canadian distributor of fastening and hardware solutions, continues to provide cutting-edge products from industry leaders like Schroff. Last year, Schroff enhanced its High Clamp Force (HC) card loks to meet the stringent Size, Weight, and Power (SWaP) requirements of military and aerospace applications, ensuring durability and efficiency in critical environments.
Military and aerospace electronics frequently operate in extreme conditions, facing high temperatures, moisture, dust, shock, and vibration. Schroff’s SWaP-compliant HC card loks offer superior printed circuit board retention and thermal management, making them particularly well-suited for surveillance systems, artillery, drones, and other defense equipment where reliability is paramount.
A key advantage of Schroff’s HC card loks is their ability to deliver three times the clamp force of traditional models. This significant improvement enhances board stability and provides greater protection against shock and vibration. The redesigned 30-degree wedge angle increases mechanical efficiency, generating greater clamping force while maintaining the same torque requirements. These components are available with multiple finishing options including black anodized, hard black anodized, or electroless nickel plating, and feature a five-segment shafted design for flexible mounting configurations.
Gould Fasteners currently stocks four distinct models of Schroff’s upgraded HC card loks, each optimized for specific applications. The Series 260HC features a 6.35 by 6.86 millimeter profile, weighs 0.95 grams per centimeter, and delivers an average clamp force of 868 pounds. The similar Series 263HC, with its slightly larger 6.35 by 7.44 millimeter profile and 1.07 grams per centimeter weight, generates 911 pounds of clamp force and is particularly effective for densely packed PCB configurations.
For applications requiring even greater performance, the Series 265HC offers a more compact 5.72 by 5.84 millimeter profile with 0.89 grams per centimeter weight while delivering an impressive 1,091 pounds of clamp force, serving as a drop-in replacement for most Series 265 applications. The screw-actuated Series 267HC completes the lineup with its 6.35 by 5 millimeter profile, 0.75 grams per centimeter weight, and 1,025 pounds of clamp force, designed as a direct replacement for most Series 267 installations.
Beyond these specialized card lok solutions, Gould Fasteners maintains a comprehensive inventory of Schroff industrial products including enclosures, subracks, chassis, and protective modules, providing complete hardware solutions for both indoor and outdoor applications across multiple industries.
