Code Blue 41542 Stainless Steel Machine Screws
Overview
The Code Blue 41542 is a 3-pack of stainless steel machine screws sized 4-40 x 1/4 inch. These fasteners secure internal components and enclosure assemblies in Code Blue audio paging and emergency communication systems. The stainless steel construction resists corrosion in both indoor and outdoor installations — a practical consideration if your towers or wall mounts see exposure to humidity, salt spray, or temperature cycling.
Compatibility
The 41542 is a replacement component for Code Blue speakerphone and paging amplifier series, including CB1, CB2, CB4, CB5, CB6, CB9, and CBRT tower and wall-mount enclosures. It is also compatible with LS1000 and LS2000 VoIP paging systems, IP1500/IP1501 solar-powered units, IP2500/IP2501 VoIP speakerphones, Centry® speakerphone units, IA4100 analog faceplate systems, and IP5000 legacy VoIP speakerphones. Check your system documentation or contact the manufacturer if you are unsure whether your specific model uses 4-40 fasteners.
Installation Notes
The 4-40 thread pitch and 1/4 inch length suit shallow recesses and thin mounting plates common in audio enclosure design. Stainless steel offers superior holding power compared to zinc-plated steel in humid or corrosive environments. Keep spare stock on hand for routine maintenance and field repairs — the 3-pack provides convenient replenishment without over-stocking.
