Meet the Hillman 7/8 in hex head cap screw — a purpose-built fastener engineered for serious strength and dependable performance in demanding assemblies. Crafted from heat-treated steel and positioned as a Grade 8 fastener, this screw is designed to resist deformation and maintain clamp force under heavy loads.
-
Size, thread, and geometry: 7/8 in hex head with 7/8-9 UNC coarse thread, 4 in length, blunt point. The sizable hex head accepts robust drivers for confident, high-torque installation and a secure drive every time.
-
Material and treatment: Heat-treated steel delivering enhanced hardness and wear resistance. This combination supports higher torque transmission and longer service life in tough environments.
-
Strength designation: Grade 8 construction, optimized for load-bearing applications where reliability matters most—think structural brackets, heavy-duty machinery mounts, and rugged framework fastenings.
-
Packaging: Boxed, with a 20-piece count per package, making it easy to stockpile for ongoing projects and avoid last-minute shortages on the jobsite.
-
Point type and application fit: Blunt point suited for through-hole assemblies in metal or wood-to-metal connections, where consistent alignment and controlled entry are priorities.
Why choose this Hillman screw over standard fasteners? It combines high-strength heat-treated steel with a bold 7/8 in hex head and a durable 7/8-9 UNC coarse thread, delivering reliable clamping force and rapid, snag-free installation. The blunt point minimizes wandering during start-up, reducing cross-threading risk in demanding setups such as equipment mounting, heavy-duty shelving frames, or structural brackets.
Ideal use cases include:
- Attaching heavy brackets to steel or timber frameworks where high shear and tensile loads are expected.
- Mounting machinery, motors, and mounting plates in industrial or workshop environments.
- Constructing rugged outdoor structures or trailer components that demand long-lasting holding power.
Pro tips for optimal results:
- Pair with a compatible hex driver or socket to prevent cam-out and ensure a solid, square seating in the head.
- Check the pilot hole size for your material and keep lubricant handy to reduce friction and improve drive smoothness in tough materials.
- Inspect threads and head after installation to confirm full seating and secure clamping, especially in vibration-prone applications.
With its heat-treated steel composition, Grade 8 designation, and 20-piece boxed packaging, this Hillman hex head cap screw is built for professionals who demand dependable performance, long-term durability, and fewer substitutions on critical assemblies. Add it to your hardware kit and experience strong, predictable fastening that stands up to real-world use.
