Value Collection 67582809 Split Lock Washer 3/8 in 316 Ss

Product Description

The VALUE COLLECTION 67582809 is a 316 stainless steel split lock washer sized for 3/8 inch screws. The helical spring design bites into the mating surface and fastener head under torque, resisting loosening from vibration and thermal cycling. Manufactured from grade 316 stainless steel, it offers strong resistance to corrosion in wet, chemical, and marine environments. The inside diameter runs 0.377 to 0.385 inches, the outside diameter runs 0.040 to 0.680 inches, and the section thickness is 0.094 inches. Licensed trades and maintenance professionals install these washers wherever fastener retention and corrosion resistance are both required.

This split lock washer is suited for mechanical assemblies, plumbing fixtures, HVAC equipment mounting, electrical enclosures, and pool or marine hardware where exposure to moisture or chemicals demands a higher-grade stainless alloy. The 316 material grade provides greater chloride resistance compared to standard 304 stainless, making it a common choice for coastal installations, chemical process environments, and applications near treated pool water. Sold individually with a minimum order quantity of 100 pieces, this washer supports bulk fastener inventory for service fleets and contractors.

Key Features

• 316 stainless steel construction for enhanced corrosion and chloride resistance
• Split helical design creates spring tension that resists fastener loosening under vibration
• Inside diameter range of 0.377 to 0.385 inches for proper 3/8 inch screw fitment
• Section thickness of 0.094 inches provides consistent locking force
• Meets ASME, ANSI, BS, DIN, JIS, and NFE standards
• Sold in bulk quantities suitable for fleet and contractor stocking

Compatibility

Designed for use with 3/8 inch screws and bolts in assemblies requiring a split lock washer. Suitable for HVAC, plumbing, electrical, and pool equipment applications where 316 stainless steel fastener hardware is specified.

Installation Notes

Installation is performed by the applicable licensed trade in accordance with the relevant assembly or equipment specifications. Place the split lock washer between the fastener head and the mating surface before driving the fastener. Ensure the mating surface and fastener are compatible with 316 stainless steel to avoid galvanic corrosion. Do not reuse compressed or fully flattened lock washers, as the spring tension will not be restored.
