Lock nuts for 3/8 inch BSW bolts that keep their grip when things shake, like a trailer, a mower or a bit of farm gear.

The nylon ring inside the top of the nut grips the bolt thread as you do it up, so it stays put without a spring washer or a second nut. They're BSW, the old Whitworth imperial thread, so check your bolt is BSW and not UNC, as the two look close but won't mix. The zinc plating suits indoor and sheltered jobs.

There are 10 nuts on the card. Full specs are in the tabs below, and if you're matching an old one, bring it in to 34-52 Milnes Rd, Strathalbyn or call us on (08) 8536 4333.
