Key Features & Benefits at a Glance
- Superior corrosion resistance with passivated 18-8 stainless steel construction, ideal for harsh environments and extended service life.
- High tensile strength of 70,000 PSI ensures reliable fastening under significant mechanical stress, reducing failure risks.
- Precise Class 2A thread fit on 3-56 UNF fine threads for smooth installation and secure, vibration-resistant connections.
- Fully threaded design maximizes grip and load distribution along the entire 3/4" length for uniform clamping force.
- Rockwell B70 hardness provides excellent durability and resistance to wear during repeated use or adjustments.
- Pan head with Phillips No. 1 drive offers a low-profile, rounded head for flush mounting and easy, tool-compatible driving.
- Compliance with ASME B18.6.3, RoHS, and REACH guarantees adherence to industry standards and environmental safety regulations.
Professional Applications & Engineering Value
Engineered for demanding industrial settings, these 3-56 UNF pan head Phillips screws in passivated 18-8 stainless steel address common challenges like corrosion, vibration loosening, and assembly efficiency. The fine UNF threading and Class 2A fit ensure tight, precise engagements in materials requiring fine pitch fasteners, such as electronics, machinery, and automotive components. The fully threaded 3/4" length enhances load-bearing capacity, while the pan head design with a Phillips drive simplifies installation in confined spaces. This combination delivers reliable performance in applications where high tensile strength and regulatory compliance are critical, minimizing maintenance and replacement costs.
Specification Summary & Compliance
This screw features a 3-56 UNF fine thread with Class 2A tolerance for precise fit, a length of 3/4", and a pan head with Phillips No. 1 drive. It meets ASME B18.6.3 specifications for dimensional accuracy and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material integrity.
