4. Durability Made from stronger materials and often treated with corrosion-resistant coatings, such screws provide added longevity, particularly in humid environments, such as bathrooms or kitchens.

2. Heavy-Duty Nail Expansion Anchors Designed for more substantial loads, these anchors provide additional holding power. They are often used in industrial settings or for mounting heavy machinery.

In the United States, ASTM (American Society for Testing and Materials) standards define the specifications for shear studs. For instance, ASTM A108 has specifications for carbon steel shear studs, which are often used due to their strength and ease of welding. The tolerances for size are usually specified to ensure consistency in performance and reliability in construction.

Bolts are among the most commonly used structural fasteners. They consist of a threaded shaft with a head at one end and are typically used in conjunction with nuts to create a strong joint between two or more components. Bolts can be found in various grades and materials, allowing for a range of tensile strengths and corrosion resistance. Common types of bolts include hex bolts, carriage bolts, and anchor bolts. Hex bolts are often used in heavy construction applications, while carriage bolts are ideal for applications where a smooth, rounded head is desired.

4. Regular Inspections After installation, periodic inspections can help identify any signs of wear or corrosion, allowing for timely repairs or replacements.
