Unlike standard steel fasteners that can quickly rust and weaken in monsoon conditions or coastal air, these bolts are crafted from high-grade stainless steel. This material offers exceptional resistance to corrosion, ensuring your projects remain structurally sound and aesthetically pleasing for years. Imported directly from authorized US retailers, they provide a reliable, long-lasting solution for outdoor applications where durability is paramount. **Ideal for Wood-to-Metal Projects, Skip if Sensitive to Imperial Sizing** — These 1/4" x 4" carriage bolts are perfect for securely joining wooden components to metal frames or other wood pieces, ideal for furniture building, decking, or fencing. The self-locking square neck ensures a tight, stable connection without needing specialized tools. However, if your project requires metric-sized fasteners or you are working with materials that only have metric pre-drilled holes, these imperial-sized bolts may not be the direct fit. Ensure you have matching imperial nuts and washers available locally. ## How to use 1. Measure the combined thickness of the wood and metal pieces you are joining. Choose a 4-inch long bolt that will pass through both materials with enough thread remaining to securely fasten a nut and washer. — Select Bolt Size 2. Drill a hole slightly larger than the 1/4-inch bolt diameter through the materials. For the square neck, ensure the hole in the first material is square-shaped or large enough for the neck to seat without turning. — Prepare Hole 3. Insert the bolt through the prepared holes. The square neck will seat itself, preventing rotation. Place a washer and nut onto the exposed threads and tighten the nut securely with a wrench. — Insert and Tighten ## Product details | Field | Value | |---|---| | Primary Use | Fastening wooden faces to wood or metal frames | | Application Environments | Outdoor use, humid conditions, coastal areas | | Cost per use | 25 bolts at ₹4,631 — ₹185 per bolt | | Shelf life after opening | Indefinite (metal fastener) | | Contraindications | Not suitable for metric-sized holes or applications requiring metric thread compatibility.

A carriage bolt has a smooth domed head and a square neck under the head that locks into wood or a squared hole, preventing the bolt from turning while you tighten the nut. It is commonly used for wood-to-wood and wood-to-metal joints such as decking, fencing, playground equipment, and timber framing. ### How do I choose the right size carriage bolt? Measure the combined thickness of the materials being joined, then add room for the washer and nut. Choose a diameter suited to the load (thicker for structural joints) and a length that leaves a few threads exposed past the nut. Match the finish to the environment — stainless or galvanized for outdoor use. ### Are these Hillman carriage bolts suitable for outdoor use in India? Yes, these bolts are made of stainless steel, offering superior rust prevention. This makes them highly suitable for outdoor applications in India, including areas with high humidity, coastal air, or monsoon seasons, where they resist corrosion better than standard steel. ### Can I use these 1/4" x 4" bolts with metric nuts? No, these are imperial-sized bolts (1/4 inch diameter, 4 inches length) with UN (Unified National Coarse) threads. They require matching imperial nuts and washers. Metric nuts will not fit these threads correctly. ### How do I buy original Hillman carriage bolts in India? Purchase from CrowCrowCrow to ensure you receive 100% original, factory-sealed products imported directly from authorized US retailers. All customs duties and GST are included in the listed price, and delivery is tracked via ExpressBox. ### What is the difference between carriage bolts and regular bolts? Carriage bolts have a smooth, domed head and a square neck that locks into the material, preventing rotation. Regular bolts often have hex heads and require a wrench on both sides to prevent turning. Carriage bolts are ideal for wood applications where a clean finish and self-locking action are needed. ## Compliance No product-specific compliance warnings identified.
