Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction, extending service life in harsh industrial environments
- High tensile strength of 60,000 psi ensures reliable load-bearing capacity for demanding fastening applications
- Rockwell B69 hardness provides excellent wear resistance and maintains thread integrity under repeated use
- Class 2A coarse UNC threads enable quick installation and reduce cross-threading risks in assembly operations
- Fully threaded right-hand design delivers maximum grip length and consistent holding power across materials
- Wide rounded binding head distributes clamping force evenly while preventing surface damage
- Slotted drive compatibility allows for versatile installation using standard hand tools
Professional Applications & Engineering Value
These 6-32 UNC coarse thread screws with zinc-plated steel construction address critical industrial fastening challenges where vibration resistance and environmental durability are paramount. The rounded binding head design prevents cable and wire insulation damage in electrical assemblies, while the fully threaded configuration ensures maximum engagement in thin materials and plastic housings. Engineers specify these ASME B18.6.3 compliant fasteners for electronics enclosures, machinery panels, and automotive components where the coarse thread pitch provides superior pull-out resistance in softer substrates. The combination of 60,000 psi tensile strength and Rockwell B69 hardness makes these slotted drive screws ideal for maintenance-intensive applications requiring repeated disassembly and reassembly.
Specification Summary & Compliance
Manufactured to precise Class 2A thread fit tolerances with UNC coarse threading (6-32 size, 0.138" diameter). These 3/8" length rounded head screws conform to ASME B18.6.3 mechanical and dimensional specifications. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring restricted substance-free components for global industrial applications.
