Engineered for dependable, long-lasting fastening, the Hillman M12 x 70 mm Hex Head Cap Screw combines high-strength steel with precision heat treatment. Designed for tough metal-to-metal connections, this M12 bolt uses a coarse 1.75 mm thread (M12 x 1.75) for quicker, more forgiving threading and robust engagement in demanding assemblies. The 70 mm length provides ample thread engagement for brackets, frames, and structural components. Each boxed package contains 20 pieces, giving you a ready supply for ongoing projects or multi-step builds.

Installation tips
For best results, use a properly sized hex socket or Allen key to avoid rounding the head. Apply a compatible thread lubricant to ease installation and reduce galling, especially in heat-treated steel. Align parts carefully to prevent cross-threading, and tighten gradually toward the recommended torque for Grade 8.8 M12 bolts. If you don’t have a torque reference, consult a standard torque chart for M12 fasteners to ensure a secure, clamped connection without overstressing materials.
Who should consider this fastener
Ideal for professional builders, fabricators, and DIY enthusiasts who need strong, long-capacity fasteners in a boxed, ready-to-use format. If you’re outfitting a workshop with dependable metric hardware or replacing worn bolts in heavy-duty frames, this Hillman hex head cap screw provides consistent performance and value.
