Southco expands captive hardware line with wing-style knob for tool-free access

Published: 6 June 2016 - Sarah Mead

Southco, the leading manufacturer of engineered access hardware solutions, has recently expanded its captive hardware line with the addition of a captive screw that offers tool-free access.

The new 4C Wing Knob Captive Screw enables quick-access fastening, and features an over-molded, wing-style head that can be used to designate access through an array of standard and bespoke colour options.

The 4C Wing Knob offers simplified positioning of sliding components, simple installation and quick-release for easy removal. Press-in, flare-in and Surface Mount Technology (SMT) options provide versatility for fastening and unfastening by hand when mounting doors, panels and other hardware components in applications where tool-free access is desired.

With extensive experience in the design and manufacture of fully xTCA-compliant hardware, Southco boasts unrivalled expertise in delivering superior solutions in terms of functionality, ergonomics and flexibility. In addition, these also satisfy the criteria for a range of other quality standards, including the  technicalities of PCI Industrial Computer Manufacturers Group (PICMG) standards affecting AdvancedTCA® (ATCA), AdvancedMC™ (AMC), and MicroTCA®.  As a member of PICMG, Southco has developed a full range of products including ejector handles, alignment/keying blocks and captive retention screws in accordance with the aforementioned standards.

Jim Grady, Global Product Manager at Southco, explained: “Southco’s newest 4C Captive Screw features a wing-style head for easy hands-on/ hands-off access and colour options that allow engineers to easily designate access points based on the unique requirements of the application. This latest innovation reflects our ongoing commitment to delivering practical solutions which address the needs of our customers and the industries they serve.”
