Hex Cap Screws

Types of Hex Cap Screws

Grade 2 Hex Cap Screws

Grade 2 hex cap screws are made from low or medium carbon steel, offering strength for general-purpose fastening. They are good for non-critical applications such as construction, machinery, and automotive assembly. Cost-and flexible, they provide dependable performance where high tensile strength is not required.

Grade 5 Hex Cap Screws

Grade 5 hex cap screws are heat-treated for higher tensile strength and hardness than Grade 2. They're designed for use in automotive, agricultural, and industrial equipment where moderate to high strength is needed. Zinc plating or black oxide finishes are often used to improve corrosion resistance and durability.

Grade 8 Hex Cap Screws

Grade 8 hex cap screws are manufactured from medium carbon alloy steel and heat-treated for maximum strength and wear resistant. They are commonly used in heavy machinery, structural assemblies, and high-stress environments. With a higher tensile rating than lower grades, they provide strong reliability in tough applications.

Stainless Hex Cap Screws

Stainless hex cap screws are the preferred choice when corrosion resistant and long-term durability are essential. Commonly used in marine, offshore, chemical processing, food service, and outdoor applications, they provide dependable performance in harsh conditions. Available in 18-8 (Type 304) for general corrosion protection and 316 Stainless for strong resistant in saltwater, chemical, and high-moisture environments.

Silicon Bronze Hex Cap Screws

Silicon bronze hex cap screws offer exceptional corrosion resistant, especially in marine and coastal environments. Non-magnetic and highly durable, they provide excellent strength and flexibility under harsh conditions. Good for boatbuilding, dock construction, and any application exposed to salt air and moisture.

Aluminum Hex Cap Screws

Aluminum hex cap screws are lightweight, corrosion resistant, and good for applications where strength-to-weight ratio is key. They perform exceptionally well in outdoor, aerospace, and electronic assemblies. Commonly chosen for projects requiring reduced weight without sacrificing durability or protection against the elements.

Hex Cap Screws Industry Applications

Hex Cap Screws are to hold heavy parts, absorb vibration, and stay tight under intense torque. From shop floors to job sites, mechanics, builders, and fabricators rely on them. In construction, they anchor steel, frame structures, and secure load bearing joints. In automotive and heavy equipment, they hold engines, suspensions, and drivetrains under heat and stress.

In manufacturing, they keep parts aligned and machines running 24/7. Designed for easy installation with Standard tools and built to withstand torque, Hex Cap Screws provide steady connections that won't loosen. With a range of materials and finishes, these fasteners adapt to nearly any job or environment.
