Meet the Hillman 7/8 in. diameter, 5 in. long heat-treated steel hex head cap screw — a decisive choice for heavy-duty joining where strength and reliability matter. Built with Grade 8 heat-treated steel, this fastener delivers exceptional tensile strength and durability for demanding projects.
Engineered for robust grip and precise torque, the hex head accepts standard wrenches or sockets, making installation quick and secure even in tight spaces. The coarse threads provide solid bite in metal applications and through-hold installations, while the blunt point helps with clean, controlled starts in through-holes or when used with a nut.
Key features that set this screw apart:
-
Head diameter: 7/8 in — a substantial head for even load distribution
-
Length: 5 in — ample reach for thicker materials or stacked assemblies
-
Material/finish: Heat-treated steel, Grade 8 for superior strength and resilience
-
Thread type: Coarse — optimized for quick, strong engagement
-
Point type: Blunt — smooth entry and consistent seating
-
Package details: 10 pieces per boxed package — ready for immediate use on multiple fastener tasks
-
Product type: Hex head cap screw — ideal for machinery, framing, and structural applications
Who should consider this fastener? Ideal for professionals and DIYers tackling metal framing, equipment mounting, or heavy-duty assemblies where a reliable, high-strength screw is essential. It’s particularly well-suited for through-bolting scenarios or securing components to tapped holes where a strong clamping force and consistent preload matter.
Practical tips for best results: pair with a matching nut or tapped hole, use a calibrated torque to avoid over-tightening, and consider a thread locker for vibration-prone environments to maintain long-term stability. Whether you’re upgrading hardware in a shop project, constructing a durable frame, or reinforcing machinery mounts, this Hillman hex head cap screw provides the proven strength and dependable performance you expect from Grade 8, heat-treated steel.
