Rivet Nut #8-32 Rubber 10 Pack

This pack contains ten rubber rivet nuts with a #8-32 thread size and a half-inch length. They are designed for blind fastening where access is limited to one side of the workpiece. The flanged neoprene bushing seals the bolt hole while providing a secure threaded insert. Suitable for automotive, marine and general repair tasks requiring vibration resistance.

Blind Fastening and Sealing Limits

The well nut design allows installation without rear access, but it requires a clearance hole matching the bushing diameter. Rubber construction limits the maximum clamping force compared to metal inserts and may degrade under prolonged exposure to petroleum-based fluids or extreme temperatures. The fastener relies on bolt torque to expand the bushing, so over-tightening can pull the nut through the rubber.

Thread Size #8-32 Determines Fit

The #8-32 thread specification is the critical dimension that decides compatibility with your bolts or machine screws. Verify that your hardware matches this exact thread pitch and diameter before purchase. Using a different thread size will prevent proper engagement and compromise the seal. This pack supplies ten pieces for multiple fastening points.

Questions about this item

Should I choose the 10-pack or a different quantity?

The listing shows a single 10-pack of #8-32 rubber rivet nuts; no other pack sizes are offered.

What does the #8-32 thread size mean when I install these?

#8-32 indicates a number-8 diameter with 32 threads per inch, so the matching machine screw will engage the embedded nut inside the neoprene bushing.

How does the rubber well-nut design limit the installation?

The flanged neoprene bushing expands as the bolt tightens, creating a sealed blind fastener that also dampens vibration in the mounting hole.
