Grade 8 (USA) Hex Cap Screws

Grade 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.
