The Hillman M6-1.00 mm x 70 mm Heat Treated Hex Head Cap Screw is built for serious fastening tasks. Crafted from steel and finished with a heat-treated temper, this screw delivers dependable strength for demanding applications, backed by a Grade 8.8 construction that resists deformation under load.
-
High-tensile strength: Grade 8.8 (property class 8.8) provides robust performance with elevated tensile and yield strength, making it suitable for joints that must endure vibration and heavy clamp forces.
-
Precise M6 coarse threading: 1.00 mm thread pitch ensures reliable engagement in tapped holes or compatible nuts, delivering steady torque transfer and secure seating in metal assemblies.
-
Generous 70 mm length: Longer reach for thicker materials or mounting blocks, reducing the need for adapters and delivering a clean, strong connection in a single fastener.
-
Hex head for easy drive: The hex head design allows quick, controlled tightening with standard wrenches or sockets, minimizing cam-out and enabling consistent torque application.
-
Bulk practicality: Boxed packaging containing 50 screws per box is ideal for workshops, service kits, and ongoing projects where you need reliable supply on hand.
-
Versatile applications: Suitable for metal-to-metal connections in machinery brackets, equipment mounting, automotive assemblies, and sturdy furniture frames where high strength matters.
Why this screw stands out: Unlike basic steel fasteners, the heat-treated finish paired with Grade 8.8 gives you a fastener that maintains clamping force under demanding conditions. The M6-1.00 coarse thread is optimized for metal threads, delivering dependable performance in standard tapped holes or with compatible nuts in a range of alloys.
