About this item

• Abrasive Material: 304 Stainless Steel with good strength, stability, and rust resistance. Surface treatment of screws adds extra protection for daily indoor/outdoor use. At the same time, high-grade 304 stainless steel delivers exceptional corrosion resistance in harsh environments—making it more durable than regular steel and zinc-plated fasteners. A square neck under the head prevents rotation during installation or use, providing anti-rotation locking and zero-maintenance integrity

• Multi-Purpose: Widely used in various places such as electronics manufacturing, machinery and equipment, chemical industry, and automotive industry, for example, snowmobiles, trailers, and agricultural machinery.
• Flexible Mounting: Featuring a round head and square neck, this bolt locks securely against rotation when fitted into pre-drilled square holes. The square neck keeps the bolt fixed during installation.
• Usage Tips: Pre-drill square holes with 0.1mm tolerance for the square neck. Drill clearance holes 0.2–0.5mm wider than the bolt shank to avoid thread damage. Ensure proper hole sizing and store in a dry environment.
