Value Collection 99218 Hex Head Cap Screw Grade 8 10 Pack

Product Description

The VALUE COLLECTION 99218 is a Grade 8 steel hex head cap screw with a 1-8 thread size and 2-3/4 inch length under head. Fully threaded along the entire shank, this fastener delivers high tensile strength across the full grip length, making it well suited for bolted connections that require consistent clamping force. The uncoated finish leaves the steel bare, appropriate for applications where secondary coating, plating, or painting will be applied after assembly. Thread form conforms to UNC standards and the screw is manufactured to ASME B18.2.1 dimensional requirements. This fastener is used by millwrights, pipefitters, maintenance mechanics, and general fabrication trades.

Grade 8 hex head cap screws in this size range are commonly used in structural assemblies, machinery mounting, heavy equipment maintenance, and industrial fabrication. The fully threaded configuration makes this screw a fit for through-bolt applications and shorter-grip connections where thread engagement across the full shank is required. Sold in a package of 10 units per the standard pack quantity for this SKU.

Installation Notes

Installation is performed by millwrights, maintenance mechanics, or structural fabricators using standard hex wrenches or impact drivers with appropriate sockets. Before installation, inspect mating threads for damage or contamination and ensure the tapped hole or nut is the correct UNC thread form. Do not mix inch and metric fasteners. Grade 8 fasteners should be torqued to values specified in the applicable engineering or equipment documentation — do not substitute published generic torque tables without confirming fastener and joint specifications.
