The obvious application is header nuts, when you have a larger than stock header. We use these all over because they are so useful. These are a LOT smaller than 11mm on the Head, and the flange keeps the header far enough away from the nut to allow your socket or wrench head enough room to get on and off! Once you use these you will never EVER go back to the Brass Nuts (that strip and round off), or the barely better 12mm ones out there. We have tried these in several different alloys (including Stainless Steel) and success with one combination was the one we used! We tried to solve them all with this product! 8mm threads, with a 10mm 6pt hex, and a 13mm flanged bottom to spread the clamping forces! You can torque these to 35lb/ft, though we feel that is excessive. We work diligently to source and fulfill your request for items as best we can.ĪCN Flanged Racing Intake and Exhaust Nut, 8 x 10mm, EACH were designed after evaluating all problems with other nuts. Requested items could be delayed by supplier-level backorder, and we usually aren't given reliable ETA information. Please only continue if you are prepared to be PATIENT. You can email to cancel un-shipped/un-paid items at any time as long as they are not special order or made/machined-to-order. For out of stock items, you are NOT CHARGED, you are automatically added to the reservation waitlist, and we post stock status / backorder info to your Order Status/History Detail View in your online Customer Account. When you place an online order request, you can opt to have in-stock items processed for shipment in advance of any backordered items. We appreciate your continued support and understanding. Even if we can't reply to your email promptly, please trust that we ARE working on getting delayed items back into stock for you, and we will contact you when we have any updated news. We are doing what we can to adapt and recover from the changes to our industry, but currently many shipments are delayed and our response time to emails are slow (we are severely short-staffed). Many sought after parts are backordered without ETA info - backorders with unreliable restock ETAs are VERY frustrating for us as well. Supply-chain disruptions have hampered our ability to restock items reliably. Your understanding is appreciated while our company struggles to weather the challenges from Covid-19, and do what we still can to support the aircooled VW hobby. We continue to answer emails as best we can, but we are operating with less than half of our normal staff, so please be patient. Restock ETAs for backordered items are often either unavailable, or unreliable. ORDER REQUESTS ARE BEING FULFILLED/SHIPPED as backordered items become available, but many popular products are delayed or in short supply. We hope that you will return when our online checkout resumes accepting new orders. Our checkout system will re-open on Saturday January 29th at 3:00pm (MST) You may want to copy and paste to save the items your cart (that includes links back to the items listings) in order to save them, just in case your browser does not. OUR ONLINE CHECKOUT is TEMPORARILY PAUSED to allow our warehouse staff time to catch up on the shipping and backorder backlog for already received orders in progress.
