Riccar Swageform Hex Washer...
$6.99
Product details
Part A732-4700 is a hex washer head screw, No. 6-32 thread, 1/4 in. long, cut in the swageform pattern. Rather than cutting a groove into the plastic, this style rolls the material outward as it turns, raising a thread of its own around the shank. That is why housings and brackets on a vacuum call for this fastener over a standard machine screw: a cut thread wears out and strips after only a couple of services, while a rolled one holds up much longer.
- Style: swageform, thread-rolling
- Head: hex washer head
- Thread: No. 6-32
- Length: 1/4 in. overall
Fasteners like this rarely get shopped for by description. Most buyers find A732-4700 by matching the callout number on an exploded parts diagram, so confirm that number against your model before adding it to the order, since bins of similar-looking screws are easy to mix up.
Do not run this screw back into a hole it has already formed and backed out of more than once or twice, because the raised plastic thread wears thinner with every removal. A fresh screw driven into that same hole restores a firm grip; reusing the old one into a loosened hole usually does not.
