On the market are numerous different kinds of bolts, screws and fasteners; some of these fasteners are widely known and widely utilized while others may be less widely recognized but no less vital - for instance knurled bolts from KIPP are notable tool-free assembly fasteners with impressed grooves on their surfaces that enable tool-free assembly - perfect for applications where regular screwdrivers cannot be used or the head needs protection from damage.
Hex bolts are among the most frequently utilized types of bolts, featuring hexagonal heads that can be tightened using a wrench. Hex bolts are frequently found in vehicles, machinery and other industrial applications - they're made from hard, strong materials that withstand high amounts of torque without losing their threads, making them easy to grip using a wrench.
Square head bolts are another popular form of bolt. These special types feature wider square heads than their hex counterparts and feature tips to assist them when placed into pre-drilled holes. Square head bolts may be more suitable than their traditional hex bolt counterparts for safety or other reasons, providing solutions in situations that don't suit traditional hex bolts as easily.
Tork bolts, commonly referred to as shear bolts, are highly specialized bolts designed to secure shear plates to concrete surfaces securely. Tork bolts can also be found securing benches or playground equipment to concrete surfaces - making them useful both in construction and gardens and parks.
Flange bolts, J-bolts and thru-bolts are also popular choices among engineers for industrial and construction use, providing additional components such as nuts, washers and shanks that have an expansion taper or expansion clip to secure structural elements like roof trusses, floor joists or wall frames.
