Fractional Sizes Grade 2 Plain Finish Bolt
Fractional Size Grade 2 Hex Head Cap Screws with Plain Finish: Reliable, Economical Fasteners for Everyday Applications
The Fractional Size Grade 2 Hex Head Cap Screw with Plain Finish is a dependable and cost-effective fastening solution for general-purpose applications. Known for its six-sided hexagonal head, this screw allows easy wrenching and secure tightening, making it one of the most widely used fasteners across industries such as manufacturing, maintenance, construction, and agriculture.
Manufactured from low or medium carbon steel, Grade 2 hex head cap screws are designed for light- to medium-duty applications where high tensile strength is not required. These screws provide dependable holding power for wood, plastic, and low-stress metal assemblies, offering versatility and ease of use.
With a minimum tensile strength of 60,000 psi (unhardened) and up to 74,000 psi when heat-treated, Grade 2 fasteners provide reliable performance in non-critical bolting applications. The plain steel finish offers an economical choice for indoor use or dry environments where corrosion protection is not essential. This uncoated surface also provides better friction for paint and plating adhesion if secondary finishing is desired.
Available in fractional (Fractional) sizes, these fasteners meet ASME B18.2.1 dimensional standards and SAE J429 mechanical property specifications, ensuring consistency and compatibility with standard nuts and washers.
