Value Collection 3BWLC904 Split Lock Washer 1/4 in Silicon Bronze

Product Description

The VALUE COLLECTION 3BWLC904 is a silicon bronze split lock washer sized for 1/4 inch screws. It is designed to resist loosening caused by vibration and dynamic loads in threaded fastener assemblies. The washer measures 0.252 inches inside diameter, 0.487 inches outside diameter, and 0.062 inches thick. Silicon bronze construction provides corrosion resistance in marine, coastal, and high-humidity environments where steel hardware would degrade. This washer is sold individually per package with a minimum order quantity of 100 units and conforms to ASME B18.21.1 standards. It is installed by tradespeople working in plumbing, marine electrical, HVAC, and general mechanical assembly applications where corrosion resistance and vibration resistance are both required.

This split lock washer is suited for residential and commercial fastener applications where a 1/4 inch screw or bolt is used and corrosion resistance is a priority. Silicon bronze is a preferred material in salt-air environments, wet mechanical spaces, pool equipment installations, and anywhere ferrous hardware would corrode prematurely. The helical split design bites into the mating surface and fastener bearing face to maintain clamp load under vibration. It is a direct drop-in for any application requiring a 1/4 inch split lock washer to ASME B18.21.1.

Key Features

• Silicon bronze material resists corrosion in marine, coastal, and high-humidity environments
• Split lock design maintains clamp load and resists loosening under vibration
• Conforms to ASME B18.21.1 fastener standard
• Inside diameter range of 0.254 to 0.262 inches fits standard 1/4 inch screw shanks
• Outside diameter range of 0.489 to 0.491 inches provides adequate bearing surface
• 0.062 inch thickness delivers consistent spring action

Compatibility

Designed for use with 1/4 inch screws and bolts in assemblies requiring an ASME B18.21.1 split lock washer in silicon bronze.

Installation Notes

Install with the split gap positioned so both ends contact the bearing surface before tightening. Power down or de-energize any assembly before disassembling fastened joints in electrical or mechanical systems. Use standard hand tools appropriate for the fastener drive type. Follow applicable codes and equipment manufacturer torque guidance for the specific joint being assembled.
