Sea-Dog Cone Point Set Screw 1/4-20 x 1/2in Stainless — Product description

Sea-Dog's cone point set screw is the little fastener that locks a knob, collar, or fitting onto a shaft and keeps it there. It's a 1/4-20 thread, 1/2 inch long, machined from 304 stainless so salt and damp bilge air don't rust it out. Hex drive, sold single.

Need to lock a knob, collar, or fitting onto a shaft and keep it there? This is the fastener that does it. Sea-Dog's cone point set screw threads 1/4-20 and runs 1/2 inch long, machined from 304 stainless so it shrugs off salt spray and damp bilge air without rusting out on you.

The cone point is the key. It drives into a matching dimple or bites into a softer shaft, giving you a positive mechanical lock that won't back out under vibration. That's exactly what you want on a boat, where everything rattles. You set it with a hex key, so there's no screwdriver slot to strip or round off down the road.

It's sold single, so grab the count you need. Common jobs: securing a shaft collar, locking a replacement knob or handle, pinning a bushing, or any spot where a screw head would get in the way. If your original hardware used a 1/4-20 set screw, this drops right in. Keep a few in the spares kit.

Frequently asked questions

What size is this set screw?

It's a 1/4-20 thread, 1/2 inch long, with a cone point and a hex socket drive. That's a common size for locking collars, knobs, and fittings onto a shaft.

What's it made of?

304 stainless steel. It holds up to salt spray and the damp conditions below deck without rusting, which is why it's a better pick than a plated steel screw on a boat.

How do I drive it?

With a hex (Allen) key that matches the socket. There's no screwdriver slot, so you won't strip a head trying to snug it down.

Does it come as a single screw or a pack?

Single. Order the quantity you need for the job plus a couple for the spares kit.
