Our Speed Nuts are made of Brass and Composite, resulting in a secure fit and ease of use. Our Speed Nuts do not require the use of washers. Superior to Standard Wing Nuts and much more superior to wing nuts made completely out of Delrin. No worry of threads stripping at the most inopportune time. Speed nuts are commonly used for attaching backplate/wing/harness systems.
The great thing about these speed nuts besides the fact they are durable and easy to use, no washers to worry about loosing! But it is still a good idea to have a spare speed nut on hand, just in case!
