Professional Applications & Engineering Value

This 1/4"-28 UNF partially threaded stud delivers exceptional engineering value through its 18-8 Stainless Steel composition and precision Class 2A thread fit. The combination of fine thread spacing and tight diameter tolerances (±0.005") ensures secure fastening in vibration-prone applications while preventing galling and cross-threading issues. The partial threading design provides both threaded engagement strength and smooth shaft versatility, making it ideal for machinery assembly, automotive components, and precision equipment where right-hand thread direction and reliable performance under 70,000 PSI loads are critical. The corrosion-resistant properties of stainless steel extend service life in demanding industrial environments, reducing maintenance frequency and total cost of ownership.
