SS Carriage Bolt

The shank of the stainless steel carriage bolt is cylindrical and usually has threads on a portion of its length. These threads allow it to be screwed into a pre-drilled hole or a nut, enabling it to securely join two or more pieces of material together. The material's stainless steel composition gives it excellent corrosion resistance, making it suitable for use in various environments, including those with exposure to moisture, chemicals, or harsh weather conditions.

Stainless steel carriage bolts are commonly used in applications such as woodworking, metal fabrication, and construction projects where a strong and durable fastening solution is required, along with the added benefit of resistance to rust and staining.

A stainless steel SS carriage bolt is a specialized fastener designed for applications requiring corrosion resistance, strength, and a smooth finished appearance. It features a distinctive domed or rounded head with a square neck beneath, which locks into the material during installation to prevent rotation. The threaded shank ensures secure fastening with a nut, making it ideal for wood-to-wood or metal-to-wood connections.

Key Features:

Material: Made from stainless steel (typically Grade 304 or 316), offering excellent resistance to rust, chemicals, and harsh environments.

Head Design: Smooth, low-profile dome head provides a finished look; the square neck grips into materials to resist turning.

Thread Type: Partially or fully threaded shank (common standards: UNC/UNF or metric).

Applications:

Outdoor structures (decks, fences, pergolas).

Marine/industrial environments.

Furniture assembly, agricultural equipment, and automotive uses.

Advantages:

✔ Corrosion-resistant – Suitable for wet or high-moisture conditions.

✔ Security – Square neck prevents spinning during nut tightening.

✔ Aesthetic – Neat, rounded head blends seamlessly into surfaces.

Common Sizes:

Diameters: 1/4" to 3/4" (or M6 to M20 metric).

Lengths: 1/2" to 12" (custom lengths available).

Note: SS carriage bolts are often specified in Grade 316 for extreme environments (e.g., saltwater exposure).
