Hex Bolts VS Carriage Bolts

HEX BOLT
  • Six sided for easy installation with a standard wrench.
  • Various strength options, grade2 to structural gradeA490
  • Ideal for metal-to-metal and metal-to-wood connections.
 
CARRIAGE BOLT
  • Smooth, rounded head for a clean install finish.
  • Set and forget- square neck ensures secure, self-locking connection.
  • Ideal for wood-to-wood connections.

Hex Nuts VS Locknuts

Finished hex nuts are general purpose and can be found in virtually endless applications making them a top choice. Furthermore, they are available in different grade options to suit almost any strength requirement. Hex nuts are generally manufactured from steel or stainless steel, among other less common materials. Selecting the best material, grade and plating is crucial to their versatility and cost effectiveness. Since they can be easily installed or removed with a wrench, they offer reusability so long as there is minimal thread damage.

Locknuts, also known as self-locking nuts, are specialized nuts designed with a unique locking mechanism to prevent loosening under vibration or dynamic loads. There are variations of locknuts, including the most common top locknut. These are constructed entirely from metal and feature deformed thread at the top, which creates friction against the bolt to “lock” it in. Available in both low carbon steel (Grade A) and higher strength carbon steel (Grade C), offers versatility based on the application's load and strength requirements. The locking design is ideal for use in high-vibration or high-motion environments. Like standard hex nuts, locknuts can be easily installed or removed with a wrench. They are also reusable, provided the threads remain undamaged and within tolerance.
 

Self Tapping Screws VS Tek Screws

Self-tapping screws are designed to tap their own threads as they are driven into base material. Commonly utilized in HVAC work, they are often referred to as sheet metal screws. Self-tapping screws perform well in other soft materials including wood or plastic. Typically manufactured from zinc-coated steel for general-purpose use, self-tapping screws are also available in stainless steel for applications requiring greater corrosion resistance. By eliminating the need for pre-tapped holes, self-tapping screws improve the assembly time and reduce labor (and cost!). Their availability in a variety of head styles and drive types makes them a versatile fastening solution across a wide range of industries and applications.

VS

Self-drilling screws, commonly referred to as Tek screws, are a staple in the construction industry, particularly for metal-to-metal and metal-to-wood connections. These screws feature a drill-point tip that allows them to drill their own hole and tap threads simultaneously. This integrated functionality makes Tek screws a preferred choice on job sites, as they save time, reduce labor (and cost!), and minimize the risk of damaging base materials. The risk of damage is a common concern when pre-drilling is required. Tek screws are appropriate for a wide range of materials, including steel, wood, aluminum, and other metals. They are typically manufactured from zinc-coated steel for general-purpose applications and are also available with other coatings such as climaseal.
