Value Collection 30725 Split Lock Washer 316 Ss

Product Description

The VALUE COLLECTION 30725 is a 3/4 inch split lock washer manufactured from 316 stainless steel. Split lock washers are used under fastener heads or nuts to resist loosening caused by vibration and torque. The helical split design bites into the bearing surface as the fastener is tightened, creating a mechanical resistance against rotation. At 0.188 inches thick with an inside diameter range of 0.753 to 0.766 inches and an outside diameter up to 1.265 inches, this washer is sized for standard 3/4 inch screw applications. The 316 alloy provides superior corrosion resistance compared to 304 stainless, making it suitable for wet, chemical-exposure, and marine environments.

This split lock washer is used in mechanical, plumbing, electrical, and HVAC installations wherever a 3/4 inch fastener must be secured against vibration-induced loosening. Typical applications include equipment mounting, pipe support hardware, conduit fittings, and structural connections in corrosive or moisture-prone environments. The 316 stainless construction makes it a common choice for coastal installations, chemical plant service, pool equipment mounting, and any application where standard carbon steel or 304 stainless would be vulnerable to corrosion. Sold individually with a minimum order quantity of 25 pieces.

Key Features

• 316 stainless steel construction for superior chloride and corrosion resistance
• Helical split design resists fastener loosening under vibration and dynamic loads
• Inside diameter range of 0.753 to 0.766 inches for precise fit on 3/4 inch screws
• Thickness of 0.188 inches provides consistent spring tension when compressed
• Outside diameter up to 1.265 inches distributes load across the bearing surface
• Inch measurement system; compatible with standard SAE fastener sizing

Compatibility

Designed for use with 3/4 inch screws and bolts in standard inch-measurement fastener assemblies. Suitable for use in mechanical, structural, plumbing, and electrical applications requiring a split lock washer in 316 stainless steel.

Installation Notes

Split lock washers are installed between the fastener head or nut and the bearing surface before final torque is applied. Power down or de-energize any equipment before servicing fastened connections. Use appropriate hand tools or a torque wrench to reach the specified fastener torque without over-compressing the washer. In corrosive environments, ensure all mating hardware is compatible stainless or non-reactive material to avoid galvanic corrosion.
