中文简体Hex cap bolts are threaded fasteners with hexagonal heads that can be installed or removed using a socket wrench, making them suitable for various projects that require strong connections that won't loosen over time. Their unique shape enables greater torque than traditional circular screws by gripping all six sides of their head simultaneously; this makes tightening much faster, as well as holding in place better once tightened, making hex bolts ideal for complex physical structures that rely on strong fasteners for stability.
Hex bolts come in an assortment of sizes, materials and finishes that makes them an excellent choice for multiple projects and industrial tasks. Common applications for hex bolts include woodworking projects involving woodworker machinery repair; construction; as well as repairs of mechanical devices used in industry. They're an indispensable addition to any tool drawer! In addition to their strength and durability, hex bolts are easily tightenable using various tools - an absolute necessity!
Hex bolts differ from other threaded fasteners in that their main feature is their hexagonal head and washer face underneath, which allow for easier tightening with a wrench, as well as providing an ample bearing surface to develop their clamp load. Hex bolts may either partially or fully threaded, with each end always capped off with a washer to ensure they won't come undone accidentally.
Like bolts, hex head caps can be made from various metal alloys. Like bolts, these caps are usually classified based on their grade or property class for SAE applications; higher grades are often designed for more demanding applications requiring increased strength and corrosion resistance; for metric applications they're usually graded according to grade class; steel options come with low, medium, and high carbon grades while stainless steel options offer increased corrosion resistance.
Hex bolts come in various finishes, from black oxide and zinc yellow platings, through zinc plating, armor coating, hot dipping galvanizing and hot dipping galvanization. Each of these coatings helps the fastener resist corrosion in harsh environments as well as protect it against rust or other forms of damage, while washers provide additional support and secure the fastener in place.
Hex tap bolts are another popular choice for use in tapped holes or with nuts. With larger diameters and typically fully threaded surfaces, they're typically provided with washer faces at either end to protect the head when being threaded through. Hex tap bolts come in various lengths depending on their design - these might include mild or stainless steel alloys as well as brass (a mixture of copper and zinc that resist corrosion), aluminum, titanium or hastelloy alloys for increased strength or hardness.
