Frequently Asked Questions
Q: What are the thread specifications for the 22256 screw?
A: The 22256 is a #2-56 UNC Phillips truss head machine screw. The size designation means number 2 diameter with 56 threads per inch. UNC indicates Unified National Coarse thread standard, and Phillips refers to the drive style.
Q: What material is the 22256 screw made from?
A: The 22256 is manufactured from 18-8 stainless steel, equivalent to AISI 304. This material provides excellent corrosion resistance, making it suitable for electric lift truck applications in wet environments or outdoor storage areas.
Q: What is the proof load rating for the 22256 screw?
A: The 22256 has a proof load rating of 39,000 psi minimum, conforming to ASME B18.6.3 specifications. This rating ensures the screw can withstand assembly stress and vibration in electric lift truck component assemblies.
Q: What is the 22256 screw used for in electric lift trucks?
A: The 22256 is used for precision fastening of small electrical components, circuit board assemblies, motor terminals, control panels, and wire management on electric material handling equipment. The Phillips drive style and truss head design provide compact securing without protrusion.
Q: Is the 22256 corrosion-resistant?
A: Yes, the 18-8 stainless steel construction provides superior corrosion resistance compared to carbon steel fasteners. This makes the 22256 ideal for electric lift trucks used in humid, wet, or cold storage environments where rust can degrade standard steel hardware.
Q: Are there alternative part numbers for the 22256 screw?
A: The 22256 is the primary OEM part number for electric lift truck applications. When sourcing replacements, specify the exact thread pitch (56 TPI), material (18-8 stainless steel), and head style (Phillips truss) to ensure compatibility with your equipment assembly requirements.
