Regulatory compliance, supply and compatibility with Satech Systems: find all the information you need here
1. Certifications and Compliance
Are the new BHC Allen Screws Regulations-compliant?
Yes. Satech's new button-head cap Allen Screw meets all captive Screw requirements specified in the Machinery Directive, while maintaining compliance with EN ISO 14120 - 5.3.9 Standards.
What are the specific requirements of EN ISO 14120-5.3.9?
The EN ISO 14120:2015 - 5.3.9 Standard (having an equivalent in ANSI/RIA 15.06) specifies that removable fixed parts of guards must only be detachable using a specific tool. Our new BHC Allen Screw requires a dedicated Screwdriver bit provided to authorized operators, ensuring installation and maintenance are performed exclusively by qualified professionals.
2. Technical Features
How is the new Screw different than the previous version?
The key enhancement is the implementation of the Allen head design, replacing the previous hexagonal head. Installation is efficiently performed using the provided dedicated Screwdriver bit.
What are the advantages of the Allen head Screw?
Allen head Screws are widely preferred across industrial and mechanical applications for several reasons. Compared to standard head Screws, they offer superior tamper resistance and enhanced protection against unauthorized access. Additionally, the recessed head design provides optimal space efficiency compared to protruding head alternatives.
4. Compatibility and Specifications
Is it necessary to replace all existing Screws?
No replacement requirement exists for current installations. The previous "Impact" Screws remain fully compliant with all Safety and regulatory requirements. However, upgrades to the new BHC Allen Screws are available through our Quick Form or your Satech representative.

Applications include all Panel/Post, Panel/Panel, and adjustable-angle connections in the ImpactGuard System, as well as upper connections and angular junctions in the FastGuard system.
Which sizes are available?
The BHC Allen Screws are offered in four sizes, accommodating all configurations from standard connections to adjustable angles for both 0.79 in. (20 mm) and 1.18 in. (30 mm) Panels.
