Short for Wi-Fi Protected Access, a Wi-Fi standard that was designed to improve upon the security features of WEP. The technology is designed to work with existing Wi-Fi products that have been enabled with WEP (i.e., as a software upgrade to existing hardware), but the technology includes two improvements over WEP:
machine bolt (a bolt with a square or hexagonal head on one end and a threaded shaft on the other end; tightened with a wrench; used to connect metal parts). kingbolt; kingpin; swivel pin (bolt that provides a steering joint in a motor vehicle).
Chain bolt for gates, doors, etc. The chain bolt may be used on the top or bottom of the gate or door, or on both the top and bottom (if two are purchased). Chain bolt provides a method of securing a gate or door in the open (or closed) position. The bolt is made of 5/8 square steel.
