Coil Bolts
Shop AFT Fasteners for all your concrete fastener needs including coil bolts. For fast assembly and disassembly of concrete forms, “coil thread” hex bolts are designed to be used with coiled thread hex nuts or coiled thread wing nuts. The "coil" thread is a large, self-cleaning thread with a rounded root thread shape (it is often advised to coat the threads with lubricant to make removal from concrete easier). Available in a wide range of lengths, you're sure to find the coil bolts you need.
