Graco 117493 390 Hexagonal Head Washer Machine Screw | Used

The Graco 117493 represents a specialized hexagonal head washer machine screw engineered for heavy-duty equipment assembly and structural fastening applications in industrial spraying systems. This used component maintains critical OEM specifications for thread pitch, shank diameter, and hexagonal drive compatibility, ensuring reliable performance in high-vibration environments and demanding operating conditions. Manufactured from grade 8 steel with corrosion-resistant plating, it provides exceptional tensile strength and shear resistance while the integrated washer head distributes clamping force evenly across fastened surfaces. The precision-machined hexagonal drive offers superior torque transmission compared to standard fasteners, reducing stripping and tool wear during installation and removal procedures in professional maintenance operations.

Frequently Asked Questions

What advantage does the integrated washer head provide?

The integrated washer head distributes clamping force evenly across fastened surfaces, prevents sinking into softer materials, and eliminates the need for separate washers in assembly applications.

Are used machine screws reliable for structural applications?

Each used machine screw is inspected for thread integrity, head condition, and structural soundness. Critical structural applications should always follow manufacturer specifications and engineering guidelines.

What torque specification should I use for installation?

Refer to your equipment service manual for specific torque values, which typically range from 20-35 ft-lbs for this size and grade of machine screw in structural applications.

Can I use a standard socket instead of a hexagonal wrench?

Yes, standard six-point sockets provide proper engagement with hexagonal heads, though ensure proper fit to prevent rounding of the head corners during torque application.

How many screws come in this package?

This package contains 1 used replacement hexagonal head washer machine screw for Graco part number 117493 with inspected mechanical integrity.
