Carriage Bolts

Delta Fitt Inc. is a leading Carriage Bolts Manufacturers that specializes in smooth headed bolts ideal in Wood-to-metal fastening and structural applications. These bolts have domed head and square neck which perfectly fix timber or metal so that they do not turn when tightening. These bolts are available in carbon steel, stainless steel and alloy steel varieties; they are the most suitable preferred bolts in decking, fencing, scaffold and bases of machinery where a smooth snag free head is required.


Our construction and industrial B2B customers can rely on our delivery of the carriage bolts in compliance with the ASTM A307, DIN 603 and ISO 8677 standards. These bolts are tested concerning head pull through resistance, thread accuracy and corrosion protection. Also, we have customization facility in terms of diameter, shank length, thread length and surface finish (galvanized, zinc plated or stainless passivation). Our effective production and logistics operations ensure that we deliver our products to our customers in both India and in our export markets including construction, agriculture and OEM industries. We supply Rock Bolts, engineered to provide reliable ground support in mining, tunneling, and civil engineering projects.


Type of Sub-products

  • Stainless Steel Carriage Bolts

    Stainless Steel Carriage Bolts

    Manufactured from SS 304 or SS 316, these bolts offer superior rust resistance and strength. Perfect for marine, food processing, and architectural applications, the stainless finish maintains aesthetics and hygiene. Their self locking square neck ensures easy installation and a flush finish in wooden walkways, playground equipment, and stainless steel structures.

  • Galvanized Carriage Bolts

    Galvanized Carriage Bolts

    These carriage bolts are hot dip galvanized to provide exceptional corrosion resistance in outdoor and marine environments. The square neck firmly locks into wood or metal, preventing bolt spin, while the domed head offers a smooth, snag free finish—ideal for decking, pergolas, and exterior structural assemblies where weather protection is critical.


Frequently Asked Questions

What materials are commonly used in manufacturing Carriage Bolts?

Carriage Bolts are typically manufactured from stainless steel (SS 304, SS 316), carbon steel, alloy steel, and hot-dip galvanized iron. These materials provide corrosion resistance, tensile strength, and long service life. Stainless steel is preferred for marine and outdoor applications due to its excellent rust resistance. Versions made of carbon steel are frequently employed for general structural applications, and all of them meet ASTM A307 or DIN 603 criteria for mechanical and dimensional consistency.

What standards do Carriage Bolts comply with?

Carriage Bolts are produced to meet global standards such as ASTM A307, DIN 603, and IS 1363. These standards define bolt strength grades, thread tolerances, and material composition. Compliance ensures they can be safely used in load-bearing wooden structures, metal assemblies, and critical construction frameworks.

How durable are Carriage Bolts in outdoor or industrial use?

Carriage Bolts are designed for long-lasting performance even in demanding environments. Stainless steel and galvanized versions resist corrosion and can withstand temperature variations, humidity, and mechanical stress. Their square neck design prevents rotation, offering a firm lock when embedded in timber or steel. Whether installed in deck construction, bridges, agricultural machinery, or railways, these bolts maintain their structural integrity under frequent load cycles.
