Locking nuts

[FraserB]

I'm looking for some secure nuts and bolts to attach the lights to my front bumper. All I have on there now are nylock and I'd rather spend $20 on some hardware than have $600 worth of LED lighting go walking off.

The only place I can really think of is Bolt Supply Warehouse.

X2. Ask for tamper-proof fasteners. You will need to buy the specific bit to install them.
