IMSCREWS M5-0.8 Metric Square Nuts - Engineered for Stability and Durability

Product Technical Specifications
Thread Size: M5-0.8 Coarse Thread
Diagonal Width: 7.8mm (Tolerance: +/- 0.2mm)
Thickness: 3.8mm
Material: High-Quality 304 Stainless Steel
Finish: Smooth, Burr-free
Package Quantity: 50 Pieces (Packed in an IMSCREWS branded ziplock bag)

Common Applications
Designed for secure fastening in confined spaces or channel slots. The flat square shape naturally resists spinning, making it highly efficient for assembling aluminum extrusion frames, machinery brackets, and outdoor hardware setups.

Frequently Asked Questions (FAQ)

Can they be used outdoors?
Yes. The 304 stainless steel construction provides reliable rust and corrosion resistance, making them highly suitable for high-humidity environments and general outdoor structural assemblies. However, they are not recommended for heavy marine or high-salt chemical applications.

Are they magnetic?
They have weak to no magnetism. It is important to note that standard cold-working processes during the manufacturing of 304 stainless steel can introduce slight magnetism, which is a normal physical property and does not affect the material's rust-resistant capabilities.

Do they come with a storage case?
No rigid storage case is included. To ensure secure transit and practical daily storage, these 50 metric nuts are thoughtfully packed in an IMSCREWS branded durable PVC ziplock bag.

Are these nuts easy to install?
Yes. The four-sided flat design prevents the nut from rotating once seated in a groove or held with a wrench, allowing for fast and efficient tightening of the matching M5-0.8 screw. Please ensure you apply standard torque and do not over-tighten to prevent thread damage.

Key Features

• [ANTI-ROTATION SQUARE DESIGN] Engineered with a flat, four-sided profile to provide excellent anti-rotation properties. Once inserted into a channel or extrusion slot, these M5 nuts stay securely in place, allowing for fast, one-sided tightening without the need to hold the nut.
• [304 STAINLESS STEEL MATERIAL] Constructed from standard 304 stainless steel with a smooth, burr-free finish. Offers high resistance to rust and oxidation, making it suitable for outdoor environments and high-humidity applications (Note: Not recommended for extreme marine or high-salt conditions).
• [PRECISE METRIC SPECIFICATIONS] Standard M5-0.8 coarse thread pitch. Diagonal width is 7.8mm with a strict manufacturing tolerance of +/- 0.2mm, and thickness is 3.8mm. Please measure your aluminum extrusion T-slot or V-slot carefully before purchasing to ensure proper fitment.
• [CUSTOM ZIPLOCK PACKAGING] Includes 50 pieces of metric square nuts securely packed in an IMSCREWS branded PVC ziplock bag for safe transit and easy daily storage. Highly compatible with standard M5-0.8 machine screws, including pan head, countersunk, and socket head cap screws.
• [VERSATILE APPLICATION & INSTALLATION TIPS] Ideal for 3D printer frames, CNC routers, robotics projects, and general structural repairs. Note: Cold-working during manufacturing may leave the stainless steel slightly magnetic, which is normal. Apply standard tightening torque to prevent stripping the threads.
