M3 Square Nut

M3 Square Nut — Mild Steel

The M3 Square Nut is engineered to provide a secure and reliable fastening solution for a variety of applications. Its distinctive square shape offers greater resistance to loosening and rotation compared to standard hex nuts, along with a larger contact surface for better load distribution across the joint.

Manufactured from mild steel, this nut delivers solid mechanical strength and durability for everyday fastening tasks. The M3 thread size pairs precisely with corresponding M3 bolts, screws, and threaded rods, making it a versatile choice across mechanical, electrical, and construction projects where a strong, stable connection is needed.

Key Applications

• Mechanical Assembly: Ideal for jigs, fixtures, and general machine building where extra grip against rotation is useful
• Electronics & Enclosures: Pairs with M3 bolts for panel mounting and small enclosure assembly
• Construction & DIY: Suited for woodworking, furniture, and general workshop fastening
• T-slot / Channel Applications: The square profile fits well into slotted channels and recesses where a hex nut would spin freely

Features

• Square profile resists loosening and self-rotation in slotted or recessed fittings
• Mild steel construction for good mechanical strength and durability
• Larger bearing surface than an equivalent hex nut, improving load distribution
• M3 thread size, compatible with standard M3 bolts and threaded rod
• Reliable, cost-effective fastening for general-purpose use

Note on finish: As mild steel, this nut is not inherently corrosion-resistant like stainless steel — recommend for indoor/dry use, or specify a plated/coated finish if outdoor exposure is expected.
