Product Details

The Marine Fasteners RP-1419 is a 100-piece pack of #12 stainless steel split lock washers built to deliver reliable fastener retention in demanding marine, automotive, and construction environments. Each washer is manufactured from 18-8 stainless steel, offering excellent resistance to corrosion, rust, and wear — making this pack equally suitable for saltwater and freshwater applications.

The split (helical spring) design creates a spring-like wedging action that bites into both the fastener and mating surface, generating friction that resists loosening caused by vibration, hull motion, and mechanical stress. These washers are sized for #12 fasteners with an outer diameter of approximately 3/8 inch.

Key Features:

  • Size: #12 (~3/8" outer diameter)
  • Material: 18-8 stainless steel for superior corrosion resistance
  • Type: Split (helical spring) lock washer
  • Quantity: 100 pieces per pack
  • Prevents fastener loosening caused by vibration and dynamic loads
  • Suitable for marine, automotive, construction, and general hardware applications
  • Compatible with #12 machine screws, bolts, and other #12 threaded fasteners

Sold in a convenient 100-piece bulk pack, the RP-1419 is ideal for maintenance, repair, and new-build projects where secure, corrosion-resistant fastening is essential.

I received my order today

Very good, Item was as expected

All good

I was charged $9.99 for shipping even though the ad stated free shipping...i was refunded $9.99 BUT i still paid tax on that $9.99 that i was not refunded. Other than that everything was all good...the megan racing muffler looks and sounds great!!! I wanted a muffler that wasnt obnoxiously loud but louder than stock and thats exactly what i got....AND the construction of the muffler is definitely good quality!!

I had to email customer service for the invoice and they got back with me immediately
