USA Manufactured Grade 5 Hex Head Cap Screw
Grade 5 Hex Head Cap Screws with Plain Finish for Industrial Use
A Grade 5 hex head cap screw with a plain finish is a versatile and dependable fastening solution used across a wide range of industrial applications in the United States. Engineered for medium-strength requirements, these fasteners deliver excellent durability, load-bearing capability, and consistent performance in automotive, construction, machinery, and maintenance environments. Their proven design and strength make them a reliable choice where secure fastening is critical.
Material and Mechanical Strength
Grade 5 hex head cap screws are typically manufactured from heat-treated medium-carbon steel such as AISI 1045 or equivalent. This material provides a strong balance of hardness and toughness, resulting in a minimum tensile strength of approximately 120,000 psi. This strength level makes Grade 5 fasteners ideal for applications that exceed the capabilities of Grade 2 hardware while avoiding the added cost of higher-strength alloy fasteners.
Plain Finish Characteristics
The plain finish offers a natural, uncoated steel surface that maintains the fastener’s original mechanical properties. While it does not provide inherent corrosion resistance, a plain finish is well suited for indoor, dry, or controlled environments. It is also preferred in applications where secondary coatings, paint, or surface treatments are applied after installation, making it common in OEM and fabrication settings.
Design, Threading, and Dimensions
Grade 5 hex head cap screws feature a six-sided hexagonal head that allows for efficient tightening with standard wrenches or sockets. The Unified National Coarse (UNC) thread design ensures easy installation, strong thread engagement, and reliable holding power. These fasteners are available in fractional sizes typically ranging from 1/4" to 1" in diameter, with lengths extending from 1/2" to 6" or longer, providing flexibility across many applications.
