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
- Material: 304 Stainless Steel; Color: Silver; Surface Treatment: Bright Finish; Screw Length: 2"; Screw Size: 3/8"-16; Screw Head Size: 3/16" x 13/16"(T x D); Washer Size: 13/32" x 1/16" x 13/16"(ID x T x OD); Hex Nut Size: 5/8" x 1/4"(Opposite Sides Width x Height); Package Content: 25 Set Carriage Bolts Screws with Hex Nut and Washer
- 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.
