Metallics JSLW41 Washers 6 Split Lock SS (Jar 100)

The JSLW41 is a #6 split lock washer, so it pairs with #6 machine screws and sheet metal screws, the size used on most device mounting screws, ground screws in small boxes, and panel cover hardware. Each jar holds 100 washers.

Stainless steel. That matters if the assembly sees damp or outdoor conditions, exterior enclosures, wash-down areas, or coastal air, where a plated or zinc washer would rust and seize the screw. Stainless also avoids galvanic issues when you are fastening into stainless hardware.

They do different jobs. A split lock washer like the JSLW41 is a single coil that spring-loads the joint and digs into the screw head and the surface, resisting loosening from vibration, thermal cycling, or repeated access. A flat washer only spreads load and protects the surface and does nothing to keep the screw from backing out. On equipment that vibrates, motor connections, or covers you expect to stay put between service visits, the split lock is the one you want, sometimes stacked over a flat washer when the hole is oversized or the material is soft.

The JSLW41 #6 split lock washer is an ANSI dimensioned part, so the inside diameter, outside diameter and section thickness follow the standard #6 pattern and it interchanges with any other ANSI #6 split lock washer already in your assemblies. Country of origin is China.

No. The JSLW41 is sized for #6 only. On a #8 or #10 screw the washer will not pass over the shank, and forcing a smaller split washer under a larger head leaves it cocked so it no longer loads the joint evenly. Order the matching #8 or #10 stainless split lock washer instead.

They come in a jar of 100, which is a jar-type pack rather than a bulk box or a loose bag. The whole package weighs about 0.1 lbs and measures 3 x 2.15 x 3 inches, so it drops into a van bin or a hardware organizer drawer without decanting.

Stainless construction holds up in damp enclosures and will not corrode away at a ground screw the way a plated washer can, which keeps the mechanical joint tight over time. Treat it as a fastener that keeps the screw from backing out, not as a listed bonding device; where a code-recognized bonding connection is required, use a bonding washer or lug specified for that purpose and keep the JSLW41 for the mechanical side.
