Low-Strength Steel Hex Head Screws
Fully Threaded
Partially Threaded
About half as strong as medium-strength steel screws, these screws can be used for light duty fastening applications, such as securing access panels. Length is measured from under the head.
Hot-dipped galvanized steel screws are 10 times more corrosion resistant than zinc-plated screws. They have a thicker coating than other finishes; to ensure compatibility, use these screws with hot-dipped galvanized steel nuts.
Match the thread spacing of mating components. Coarse threads are the industry standard; choose these screws if you don’t know the threads per inch. Screws that meet ASTM A307 or SAE J429 comply with specifications and testing requirements for material quality. Screws that meet ASME B18.2.1 or ASME B18.6.3 comply with specifications for dimensional standards.

Medium-Strength Steel Heavy Hex Head Screws for Structural Applications
Fully Threaded
Partially Threaded
The most common heavy hex head screw, these steel screws meet ASTM A325 regulations for structural joints, such as mating I-beams and scaffolding. Material meets ASTM F3125 specifications for quality. Dimensions meet ASME B18.2.6 specifications. Length is measured from under the head.
Partially threaded screws come with precise threaded and unthreaded portions, allowing you to place only the stronger unthreaded portion (grip) in joints subjected to sideways forces.
Hot-dipped galvanized screws have a thick coating for excellent corrosion resistance. To ensure compatibility, use these screws with hot-dipped galvanized steel nuts.

Metric High-Strength Steel Heavy Hex Head Screws for Structural Applications
Designed for construction, these metric screws are often used to join I-beams and scaffolding. They’re Class 10.9 steel, which is at least 25% stronger than medium-strength steel. Since the head is 10% wider than a standard hex head, it spreads force over a larger area, and you can tighten these screws with more torque. They also have a precisely measured unthreaded section under the head, called a grip. It’s stronger than the threaded section, so you can place it in joints exposed to sideways force. All screws meet EN 14399 (formerly DIN 6914 and ISO 7412) standards for dimensions. Length is measured from under the head.
Hot-dipped galvanized steel screws are 10 times more corrosion resistant than zinc-plated screws, so they resist rust in wet areas. The finish is thicker than other finishes, so these screws are compatible with only hot-dipped galvanized steel fasteners. To meet structural standards, use them with hot-dipped galvanized structural hex nuts and washers.

Steel Hex Head Screws for Wood
These steel screws have corrosion-resistant finishes. Also known as lag bolts, they have a hex head for a secure grip with a wrench. They press threads into material for a tight, secure hold. To prevent splitting, drill a pilot hole slightly smaller than the screw. Length is measured from under the head.
Hot-dipped galvanized steel screws have a thick coating for better corrosion resistance than zinc-plated steel screws. They're a good choice for ACQ-treated (arsenic-free) lumber.

Steel Flanged Hex Head Screws for Wood
These steel screws are hot-dipped galvanized to resist corrosion in wet environments and are a good choice for ACQ-treated (arsenic-free) lumber. The flange reduces the risk of crushing material and the hex head provides a secure grip with a wrench. They press threads into material for a tight, secure hold. To prevent splitting, drill a pilot hole slightly smaller than the screw. Head height includes the flange. Length is measured from under the head.
