The Multiquip 3053416 is a genuine OEM Hex Jam Lock Nylon Nut 3/4-16 UNF designed for MQ diaphragm pump models including MQ-D305, D306, and MQ-D306HA. As a direct OEM replacement, part 3053416 is manufactured to the exact thread specification and nylon insert grade required for secure, vibration-resistant fastening in Multiquip diaphragm pump assemblies. Sourced directly through authorized Multiquip supply channels, this nut ensures a correct, confident fit every time. DHS Equipment stocks genuine Multiquip OEM parts so you can get your pump back in service fast.
Key Features
- Nylon Insert Locking Action: — The nylon collar grips the thread under vibration and torque load, preventing the nut from backing off during pump operation.
- Exact Thread Specification: — Threaded to 3/4-16 UNF, this nut seats and torques correctly against mating fasteners without reworking or chasing threads.
- Genuine OEM Construction: — Manufactured to Multiquip's material and dimensional spec for the hex jam lock profile, ensuring the locking insert performs at rated capacity rather than approximating it.
- Confirmed Fitment: — Verified for MQ-D305, D306, and MQ-D306HA diaphragm pump models — consult your parts manual to confirm the correct position before installation.
- Keeps Critical Assemblies Secure: — A loose or failed jam nut on a diaphragm pump can allow connected components to shift under pressure cycling, leading to leaks or accelerated wear at fastened joints.
A hex jam lock nylon nut is a low-profile fastener fitted with a nylon insert that deforms slightly around the mating bolt thread when torqued down, creating a friction-based lock that resists loosening from vibration and pressure fluctuation. On a diaphragm pump, fasteners are subject to repeated pressure cycling and mechanical vibration with every stroke, making locking fasteners essential at critical joint locations. When a jam nut loses its locking torque — through wear, over-cycling, or use of an incorrect replacement — connected components can work loose, potentially causing fluid leaks, misalignment, or damage to surrounding parts.
