Metric 8.8 Hex Cap Screws at Empire Bolt & Screw

Metric 8.8 Hex Cap Screws are very common fasteners found in manufacturing, repair and construction industries worldwide.  They are used to fasten 2 or more parts together in an assembly that may require future repair or maintenance disassembly.  Their six-sided hex head allows for a more substantial bearing and wrenching surface than what socket products or machine screws can provide, thereby making them the clear choice in many complex and heavy duty applications. 
 
Metric 8.8 Hex Cap Screws are manufactured from medium carbon steel and are heat-treated, quenched and tempered.  With a proof load of 580 MPa and minimum tensile strength of 800 MPa, their strength is most similar to Grade 5 and considered mid-range.  They are easily identified with the unique head stamp of 8.8 and are most commonly available in plain finish, and clear electro-zinc plate.
