Types of Hex Cap Screws
Grade 2 Hex Cap Screws
Grade 2 hex cap screws are made from low or medium carbon steel, offering reliable strength for general-purpose fastening. They are ideal for non-critical applications such as construction, machinery, and automotive assembly. Cost-effective and versatile, 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 enhance 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 resistance. They are commonly used in heavy machinery, structural assemblies, and high-stress environments. With a higher tensile rating than lower grades, they provide superior reliability in demanding applications.
Stainless Hex Cap Screws
Stainless hex cap screws are the preferred choice when corrosion resistance 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 superior resistance in saltwater, chemical, and high-moisture environments.
Silicon Bronze Hex Cap Screws
Silicon bronze hex cap screws offer exceptional corrosion resistance, especially in marine and coastal environments. Non-magnetic and highly durable, they provide excellent strength and flexibility under harsh conditions. Ideal for boatbuilding, dock construction, and any application exposed to salt air and moisture.
Brass Hex Cap Screws
Brass hex cap screws combine corrosion resistance with superior electrical conductivity and a polished, decorative finish. They’re non-magnetic and easy to machine, making them ideal for plumbing, electrical, and architectural applications. Perfect for projects requiring both functionality and visual appeal.
Aluminum Hex Cap Screws
Aluminum hex cap screws are lightweight, corrosion resistant, and ideal 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 trusted 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.
