For dependable, professional mounting in security, surveillance and low-voltage installations, choose the Dottie 5MB14312 1/4"-20 x 3-1/2" Hex Head Cap Screw. These Grade 5 screws, made from medium carbon steel, provide the controlled clamp force and medium-strength performance required for camera mounts, access control assemblies and other physical security hardware. With a 3.5" length and 1/4"-20 (20 TPI) thread, the cap screw offers deep engagement in internally tapped holes or when used with a nut—helping prevent loosening in monitoring equipment exposed to vibration.

Manufactured to SAE J429 and ASME B18.2.1 dimensional standards, these hex cap screws reduce rework and ensure consistent joint performance across installations. Supplied in a convenient pack of 100, they simplify procurement for contractors and systems integrators handling multiple mounting points. Note: use with a hardened washer under the turned component to preserve clamping surfaces. Ideal for professional security integrators and network technicians mounting surveillance cameras, racks or enclosures.
