Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding environments
- Precise Class 2A thread fit ensures smooth installation and reliable fastening in fine-thread applications
- High tensile strength of 60,000 psi provides exceptional load-bearing capacity for critical assemblies
- 82° countersink angle with standard flat head profile enables flush mounting and clean aesthetic finishes
- Full threading along 7/8" length offers maximum grip range and adjustment flexibility
- Rockwell B70 hardness rating maintains thread integrity and prevents stripping during repeated use
- Slotted drive compatibility allows installation with standard tools while minimizing head protrusion
Professional Applications & Engineering Value
Engineered for precision assemblies requiring low-profile fastening solutions, these 10-32 UNF flat head screws address common industrial challenges like vibration-induced loosening and corrosion. The zinc-plated steel construction provides a sacrificial layer that protects against oxidation in humid or outdoor environments, while the fine thread spacing and Class 2A fit ensure tight tolerances for machinery, electronics enclosures, and automotive components. The 82° countersink angle allows seamless integration into tapered holes, eliminating snag points in conveyor systems or production equipment. These fully threaded fasteners distribute clamping force evenly across the entire 7/8" length, making them ideal for securing thin sheet metal, plastic housings, and precision instruments where space optimization is critical.
Specification Summary & Compliance
Manufactured to ASME B18.6.3 specifications with Class 2A thread fit and UNF fine thread form in right-hand direction. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Dimensional accuracy maintained per inch system standards with 0.362" head diameter and 0.116" head height.
