Unbranded M6-1.0 x 20 mm Class 8.8 Metric Zinc Plated Steel Hex Head Cap Screws (25-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.
