Engineered by Hillman for demanding joints, the M8-1.25 x 70 mm Hex Head Cap Screw delivers dependable strength when you need a reliable, longer-fastening solution. Built from heat-treated steel and graded 8.8, this fastener is designed to hold up under higher torque and tougher loads than standard screws, making it a smart choice for heavy-duty projects.
-
Material and hardening: Heat-treated steel with a Grade 8.8 specification provides enhanced tensile strength, improved wear resistance, and longer service life in challenging assemblies.
-
Thread and fit: Coarse M8-1.25 thread offers quicker alignment and strong bite in softer metals or engineered woods, making installation faster and more forgiving on misaligned holes.
-
Head design: Hex head enables straightforward driving with common wrenches or socket tools, delivering solid torque transfer for secure, lasting joints.
-
Size and compatibility: 70 mm length is ideal for through-hole mounting or joining thicker components, paired with standard nuts or tapped holes designed for metric hardware.
-
Finish and durability: Heat-treated finish enhances hardness and reliability in a boxed, ready-to-use package, ensuring you have a durable fastener for time-sensitive jobs.
-
Packaging: Boxed packaging keeps 40 pieces neatly organized and protected, simplifying reorder workflows and reducing downtime on larger projects.
This screw shines in a variety of real-world applications. Use it for securing heavy brackets to steel frames, mounting equipment on machinery, fortifying metal shelving, or assembling strong, long-reach connections in automotive or industrial projects. It’s particularly effective when you need a high-torque fastener that resists loosening under vibration, yet remains compatible with common metric tooling.
Ideal for: professional builders, metal fabricators, DIY enthusiasts tackling furniture frames, equipment mounting, or any project requiring a robust, long hex-head fastener with reliable performance.
Choosing the right fastener matters—here’s why this Hillman screw stands out:
- Superior strength with heat-treated steel and Grade 8.8 designation translates to better load-bearing capacity and reduced risk of thread stripping in demanding joints.
- Long 70 mm length provides versatility for thicker assemblies or through-hole connections where a deeper engagement is beneficial.
- Coarse M8-1.25 threading balances ease of installation with dependable grip, especially when working with softer base materials or when precise threading isn’t perfectly aligned.
Practical tips for best results
- Pair with a compatible nut or tapped hole designed for M8-1.25 threads to ensure optimal engagement.
- Use a washer when mounting soft materials to distribute load and reduce pull-through risk.
- Avoid over-torquing—start with a conservative torque and increase gradually to achieve a secure fit without stripping the thread.
- Store in the original boxed packaging to preserve organization and protect from moisture and corrosion.
