Why this screw stands out
Designed for durability in demanding environments, this Hillman fastener combines heat treatment with a zinc finish to resist wear and corrosion over time. The 8.8-grade steel delivers strong, consistent clamp load, making it ideal for assemblies that endure vibration, outdoor exposure, or heavy loading. The coarse M12 thread speeds installation and reduces the risk of cross-threading when aligning components, while the long 90 mm length provides versatility for thicker materials or multiple seating depths.
Ideal use cases
- Heavy-duty machine frames and brackets where a secure, high-torque connection is needed
- Automotive and outdoor equipment assemblies that require corrosion resistance
- Industrial furniture, shelving, and cabinetry where reliable, repeated assembly is common
- Mounting components to metal panels or thick substrates that demand a robust fastener
Practical tips for best results
- Pair with matching nuts or pre-tapped holes and consider washers to distribute load and protect surfaces
- Ensure compatibility with M12 coarse-threaded holes or nuts to maximize engagement and clamp strength
- Follow standard torque guidelines for M12x1.75 in your material to avoid over-tightening or bearing stress
- Store in the boxed packaging to keep the 15-piece set organized and ready for quick replacements
