Unbranded 5/16 in.-18 x 1 in. Nylon Hex Head Cap Screws (10-Pack)

Hex head cap screws are similar to hex bolts, but feature a washer surface under the head and have a chamfered end (as opposed to the flat end seen on hex bolts). They are often called finished hex bolts. The 6-sided head makes them easy to install using a standard wrench or socket set.
