Construction fasteners must match the joint, load, material, and jobsite environment. A correct fastener is not only the right size. It must also have the correct grade, thread, coating, washer support, and installation method.<\/p>\n\n\n\n

For project buyers, the safest rule is simple: specify the full fastening assembly before requesting a quote.<\/p>\n\n\n\n

Main Fasteners Used in Construction<\/h2>\n\n\n\n

Bolts for Steel and Equipment Connections<\/h3>\n\n\n\n

Bolts are used in steel frames, base plates, brackets, platforms, machinery supports, and temporary structures. Common construction bolts include hex bolts, heavy hex bolts, flange bolts, carriage bolts, and structural bolts.<\/p>\n\n\n\n

Anchors for Concrete Fixing<\/h2>\n\n\n\n

Selection Depends on Concrete and Load<\/h3>\n\n\n\n

Anchors transfer load into concrete or masonry. They are used for base plates, pipe supports, machinery bases, handrails, brackets, and structural attachments.<\/p>\n\n\n\n

Common types include wedge anchors, sleeve anchors, drop-in anchors, chemical anchors, expansion anchors, and cast-in anchor bolts.<\/p>\n\n\n\n

Anchor selection must confirm:<\/p>\n\n\n\n

    \n
  1. \u6df7\u51dd\u571f\u5f3a\u5ea6<\/li>\n\n\n\n
  2. \u5b54\u5f84\u548c\u6df1\u5ea6<\/li>\n\n\n\n
  3. \u57cb\u7f6e\u6df1\u5ea6<\/li>\n\n\n\n
  4. \u8fb9\u8ddd<\/li>\n\n\n\n
  5. \u951a\u6746\u95f4\u8ddd<\/li>\n\n\n\n
  6. Tension, shear, or combined load<\/li>\n\n\n\n
  7. Cracked or uncracked concrete condition<\/li>\n<\/ol>\n\n\n\n

    Anchor capacity should never be estimated from diameter alone. Installation quality directly affects performance.<\/p>\n\n\n\n

    Washers for Load Distribution<\/h2>\n\n\n\n

    Small Part, Critical Function<\/h3>\n\n\n\n

    Washers distribute clamp force, protect contact surfaces, reduce embedment, and help maintain preload. In structural or high-strength joints, washer hardness matters.<\/p>\n\n\n\n

    Match the Site Condition<\/h3>\n\n\n\n

    Construction fasteners may be carbon steel, alloy steel, stainless steel, or coated steel. Load-bearing joints may require \u9ad8\u5f3a\u5ea6\u7d27\u56fa\u4ef6<\/a>.<\/p>\n\n\n\n

    Outdoor projects usually need corrosion protection. Options include zinc plating, hot-dip galvanizing, zinc flake coating, or stainless steel. For corrosion-focused orders, compare \u5404\u79cd\u6d82\u5c42\u7d27\u56fa\u4ef6<\/a>.<\/p>\n\n\n\n
