1/4"-28 Zinc Grade 5 Steel Fine Thread Hex Bolt Cap Screws
Our Grade 5 Steel Fine Thread Hex Cap Screws provide a reliable and durable fastening solution for medium-strength applications. Engineered for performance and longevity, these cap screws are a staple for automotive, mechanical, and construction projects where precision and strength are paramount.
Each screw is manufactured from high-quality steel and features a zinc-plated finish, offering enhanced corrosion resistance and a clean, professional appearance. The Grade 5 hardness rating ensures these fasteners can withstand significant stress and tension compared to standard low-carbon steel bolts. The fine thread design (28 TPI) provides superior vibration resistance and allows for finer adjustments in delicate assemblies.
The hexagonal head is specifically designed to be driven by a standard 7/16" wrench, allowing for maximum torque application without the risk of slipping. Whether you are performing routine maintenance or tackling a complex build, these hex cap screws offer the consistency and industrial-grade quality you need to get the job done right.
