Value Collection BWSI025-100BX Belleville Disc Spring

Product Description

The VALUE COLLECTION BWSI025-100BX is a Belleville disc spring sized for 1/4-inch bolt applications. Also called a conical washer spring or coned-disc spring, this fastener component generates high clamping force in a compact axial space. It features a 0.252-inch inner diameter and a 0.394-inch outer diameter, making it a direct fit for 1/4-inch fastener assemblies. Belleville springs are specified when a load must be maintained under thermal cycling, vibration, or bolt relaxation. Maintenance technicians, mechanical assemblers, and field service technicians across HVAC, plumbing, and industrial trades use these springs in bolted joint assemblies to preserve preload.

This disc spring is suited for residential and light commercial applications where 1/4-inch fasteners require controlled spring force. Common install scenarios include flanged pipe joints, equipment mounting brackets, valve assemblies, and electrical panel hardware where joint integrity must be maintained over repeated thermal or mechanical cycles. The small diameter profile allows use in confined bolt patterns with limited clearance. Sold in a minimum order quantity of 100 pieces, this part is appropriate for service shops, maintenance departments, or contractors stocking consumable fastener hardware.

Key Features

• 0.252-inch inner diameter fits standard 1/4-inch bolt shanks
• 0.394-inch outer diameter for compact fastener assemblies
• Steel construction for durability under mechanical and thermal load
• Conical disc profile maintains clamping force under vibration and bolt relaxation
• UNSPSC code 31161825 for procurement and catalog alignment

Compatibility

Designed as a Belleville disc spring for 1/4-inch bolt size applications. Verify inner diameter, outer diameter, and load requirements against the assembly specification before installation.

Installation Notes

Installation is performed by mechanical assemblers or trade technicians working on bolted joint assemblies. De-energize or depressurize the system before disassembling any joint. Orient the disc spring correctly per the assembly drawing, as stacking orientation affects load and deflection characteristics. Torque fasteners to the assembly specification using a calibrated torque wrench.
