64304075 - 1/4-Inch Plain Flat Washer, Steel Zinc Plated (0.250 ID)

Reliable Hardware for Welding & Fabrication Shops

In a busy welding and fabrication environment, the smallest components often play the biggest roles in keeping operations running smoothly. The 1/4-Inch Plain Steel Flat Washer (Zinc Plated) is a staple item for welders, fabricators, and shop technicians. Identified by the code "WSR PLAIN STLZPC .250", this washer is engineered to meet the rugged demands of shop equipment repair and jig construction. When building custom fixtures or repairing welding carts, having the right hardware on hand prevents downtime and ensures that every connection is secure and professional.

This washer is manufactured from robust steel, providing the hardness necessary to withstand the torque applied during fastening without deforming. The 0.250-inch inner diameter is precision-sized for 1/4-inch fasteners, a common size found on welding power sources, wire feeders, and gas cylinder cages. The "STLZPC" designation indicates a Zinc Plated Clear finish. For a welder, this is important because it resists the corrosion often caused by the humid and fume-rich environments found in metalworking shops. While welders should always be cautious about welding near zinc-plated hardware due to fumes, these washers are excellent for cold-fastening applications where welding is not involved.

Beyond simple repairs, these flat washers are invaluable for creating temporary fit-ups and spacing in fabrication jigs. Their consistent thickness allows them to be used as shims to level parts or adjust spacing before tack welding. Furthermore, when mounting accessories like torch holders, ground clamps, or hose reels, using a flat washer ensures that the mounting bolts do not loosen over time due to the vibrations caused by grinders and heavy machinery. It is a simple, low-cost solution that adds longevity and safety to shop equipment.

Shop Applications:

• Equipment Repair: Ideal for replacing missing hardware on MIG/TIG machines and plasma cutters.
• Fixture Building: Use as spacers or bearing surfaces in custom welding jigs.
• General Mounting: Securely mount regulators, flowmeters, and safety gear to walls or carts.
• Vibration Management: Helps maintain bolt tension on vibrating shop tools.
