Dottie 5MB38114 Screw, 3/8"-16 1-1/4" Grade Hex Head Cap Screw

Secure high-load assemblies and critical surveillance mounts with the Dottie 3/8-16 x 1-1/4 Grade 5 hex head cap screw. Designed for contractors and security integrators, this carbon steel cap screw delivers consistent clamp force where reliable fastening matters — from camera brackets and access control enclosures to rack-mounted equipment. The 3/8-16 thread (16 TPI) and 1-1/4" length work with internally tapped holes or nuts, while the zinc-plated finish improves corrosion resistance for long-term performance in monitoring and security environments.

Manufactured to SAE J429 and ASME B18.2.1 standards, Dottie’s hex head cap screw gives you the balance of medium strength and predictable torque control needed when installing surveillance systems, network racks, and physical security hardware. Supplied in a convenient 100-pack, it streamlines procurement and keeps field crews moving. For best results, pair with a hardened washer under the turned component to protect surfaces and maintain clamp integrity.
