5/16-18 Threaded Rubber Feet & Vibration Mounts

(24 products)

These parts share a 5/16-18 thread: 5/16" diameter with 18 threads per inch. It is a step up from 1/4-20 and is common on compressor and pump bases, machine stands, generators and heavier furniture. The collection covers male/male isolator mounts, male/female mounts and adjustable leveling feet with 5/16-18 studs or female threads, in diameters from about 3/4" to 1-1/2".

Choosing a size. Confirm the thread with a 5/16-18 nut or a thread gauge, since 5/16-24 fine thread and M8 are close in diameter but are not interchangeable. Next, measure the free height you need between the two surfaces and pick a rubber height that fits it. For stud length, measure the depth of the tapped hole or the thickness of the bracket plus room for a nut and washer. If your old mount has a stud on one side and a threaded hole on the other, look for the male/female versions.
