ASMC Industrial 1/4"-20 x 1 1/4" (FT) Coarse Thread Grade 5 Carriage Bolts - Durable Hardware Fasteners for Wood, Metal, Furniture Works and Repair, Medium Carbon Steel, Black Oxide - Pack of 100

These 1/4"-20 carriage bolts fix that problem completely. The square neck grips into wood, so you only need one wrench - no more wrestling with two tools or having your buddy hold the other end. They're made from medium carbon steel with Grade 5 strength that's way stronger than the cheap bolts you find at most stores, so each 1/4 bolt can handle over 3,000 pounds without breaking. That's more than enough for any furniture or construction project you're working on. The 1 1/4" length works great for joining wood pieces or connecting them to metal brackets, and the 1/4-20 thread fits standard nuts and bolts and washers from any hardware store - no hunting for weird sizes or special orders. The black oxide coating looks clean on visible spots like a headboard, and the smooth dome head feels good if you accidentally brush against it, unlike sharp hex bolts that can scratch or catch. You get 100 bolts in this bolt kit, which costs way less than buying them individually and means you'll have extras for future repairs or unexpected projects. These work well for indoors or in covered areas since they're not designed for constant rain, but they're ideal for furniture makers, workshop projects, garage storage systems, or anyone doing construction work where you need reliable fasteners and bolt and nut set combinations that actually stay tight. Whether you're building crib rails, assembling benches, or fixing storage shelves, these black bolts will solve those spinning problems for good.

• SQUARE NECK STOPS THE SPINNING: You know how regular bolts spin when you're trying to tighten them? These carriage bolts have a square section that grips the wood, so you only need one wrench. Just drill your hole, slide the 1/4 bolt through, add a carriage bolt and 1/4-20 nut, then tighten. No more frustration trying to hold both sides - the square neck does that work for you. Works great for furniture bolts projects and construction, where nuts and bolts need to stay put.
• STRONG ENOUGH FOR REAL WORK: These aren't the cheap bolts you get at discount stores. Made from medium carbon steel with grade 5 strength, so a single 1/4 bolt can handle over 3,000 pounds before it gives up. Contractors use thousands of these carriage bolts every day in construction because they don't bend or break under normal loads. Whether you're building furniture or doing repair work, these fasteners and bolt kit components won't let you down when nuts and bolts assemblies matter most.
• IDEAL FOR WOOD PROJECTS: The 1 1/4" length is just right for joining wood pieces or connecting wood to metal brackets in furniture and construction work. The 1/4-20 coarse thread fits standard nuts and bolts, and washers from any hardware store - no hunting for weird sizes. Great for furniture, decking, or any project. This bolt and nut set grabs tight and won't strip out like fine threads do when working with softer materials.
• LOOKS GOOD ON VISIBLE SPOTS: The black oxide coating gives these a clean, finished look that won't stick out like plain steel bolts. The smooth dome head sits flush and feels comfortable if you brush against it - no sharp edges like hex bolts. Ideal when you're making a headboard or bench where people will see and touch the hardware. The black finish on this bolt set also helps hide minor scratches and fingerprints more effectively than shiny metal finishes in furniture applications.
• INDOOR USE WITH GREAT VALUE: This pack gives you 100 bolts - way cheaper than buying individual nuts and bolts one at a time. Having extras means you can fix things later without another store trip. This bolt kit works best indoors or in covered areas since the coating handles humidity but not constant rain. Ideal for furniture makers, workshop storage, or anyone who likes having the right bolt and nut combo with matching washers ready when construction projects need black nuts and bolts.
