30Cu Parts

A replacement hex head cap screw sized 3/8-16 x 4.5 that secures cabinetry and mechanical components on compatible appliances. Restores proper fastening and helps eliminate looseness or rattling. What it does:

• Fastens panels, brackets, or structural parts where a 3/8-16 x 4.5 hex head screw is specified
• Replaces missing or damaged screws that cause loose or vibrating panels
• Helps maintain alignment of mounted assemblies and moving parts
• Used where a durable machine screw with coarse 16-thread engagement is required

• One hex cap screw (3/8-16 x 4.5)

• Disconnect power and water before beginning any repair
• Use the correct 3/8" socket or wrench for installation; tighten securely but avoid overtightening
• Verify screw fits the mating hole and threads smoothly before final torque
• If replacing multiple fasteners, install all like-for-like to maintain proper alignment
