About this item
- Abrasive Material: Carbon Steel – This carriage bolt features an extra-large round head for a larger contact surface and higher-stress applications than standard round head square neck bolts. Made of quality carbon steel with high strength, good rigidity, and excellent resistance to breakage and bending. The square neck beneath the round head prevents bolt rotation during installation and use, ensuring a stable assembly and a secure connection.
- Specification: Material: Carbon Steel; Color: Blue-White; Surface Treatment: Galvanized; Screw Size: 5/16"-18; Screw Length: 1-1/2"; Screw Head Size: 0.165 x 0.7 x 0.31"(T x D x Square Neck Width); Package Content: 100 Pcs Carriage Bolts Screws
- Multi-Purpose: Suitable for wood-to-wood or wood-to-metal indoor fastening. Suitable for home DIY projects, furniture assembly, bed frames, tables, chairs, garage doors, cabinet installation, and general household maintenance. It provides stable and firm connections for daily indoor applications.
- Flexible Mounting: The round head with square neck design allows anti-rotation locking when installed into a pre-drilled square hole. The square neck holds the bolt in place and prevents rotation 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 sizes to prevent looseness or difficult installation. Store in a dry environment to maintain the surface condition.
