FAQ
BUNG ADJUSTER NUT Frequently Asked Questions
What is the BAN-8-6 bung adjuster nut used for?
The BAN-8-6 fits into a weld-in tube bung and accepts a rod end or linkage component on its internal thread, while the external thread connects to a tube adapter or threaded housing. It allows fine length adjustment in suspension links, steering tie rods, and push-pull control rods.
What are the internal and external thread specs of the BAN-8-6?
Internal thread is 3/8-24 RH and external thread is 1/2-20 RH — confirm both against the tube bung and the rod end or adapter you're threading into before ordering.
What's the difference between the BAN-8-6 and the BANL-8-6?
BAN-8-6 and BANL-8-6 are a matched right-hand/left-hand pair on the same thread sizes — BAN-8-6 is threaded 3/8-24 RH/1/2-20 RH, while its counterpart uses the opposite hand on both ends. Use the matched pair on a turnbuckle-style double adjuster, or order the single hand that matches your existing tube bung and rod end threads.
What are the hex size and length of the BAN-8-6?
Hex size is 0.563" across flats, hex length is 0.219", and total length is 1.25" — check the hex size against your wrench/socket and the total length against your available adjustment space.
What material is the BAN-8-6 made from?
The BAN-8-6 is made from 4130 chromoly steel with a silver zinc-plated finish.
What does the BAN-8-6 pair with, and can SYZ supply special sizes?
It's paired with tube adapters (WTF series) and rod ends to build a complete adjustable linkage assembly. Special sizes and plating options are available in volume — provide your target thread sizes and quantity when requesting a quote.
