FAQs of Square Neck Carriage Bolt:

Q: How are Square Neck Carriage Bolts typically used in construction and furniture assembly?

A: Square Neck Carriage Bolts are inserted through pre-drilled holes in wood or metal, with the square neck ensuring a snug, non-rotating fit during tightening. Theyre especially useful in wooden joints or applications where a smooth, rounded head is required for safety or appearance.

Q: What materials and finishes are available for these bolts, and how do they benefit the end-use?

A: These bolts are offered in carbon steel, mild steel, stainless steel (A2, A4), and alloy steel. Surface treatments such as zinc plating, hot dip galvanizing, and black oxide enhance resistance to corrosion, making them suitable for environments exposed to moisture or chemicals.

Q: When should I choose a specific grade (like 4.6, 8.8, or 10.9) for my application?

A: Select the grade based on the required tensile strength for your project. Lower grades like 4.6 are suitable for light-duty fastening, while higher grades like 8.8 and 10.9 are ideal for high-stress or heavy-load applications.

Q: Where are these carriage bolts manufactured and supplied?

A: These bolts are manufactured using cold forging and machining processes in India and are distributed, exported, supplied, and traded nationally and internationally by leading industry players.

Q: What options are available for thread type and direction?

A: The bolts come with right-hand threading and offer various thread types including Metric, UNC, UNF, and BSW to accommodate different regional and industry standards.

Q: How does the square neck design improve bolt performance?

A: The square neck beneath the round head prevents the bolt from spinning as the nut is tightened. This provides a secure installation, especially valuable when fastening soft materials like wood, where slippage is common with standard round bolts.
