Delrin washers protect your razor's finish and threads. Learn why they matter and how to install them correctly with our step-by-step guide.

Quick answer

Yes, you should use a Delrin washer on your safety razor. Placed between the handle and base plate, it prevents scratches, reduces thread wear, and can act as a spacer for thin base plates. Installation takes seconds and costs pennies.

Why a tiny washer makes a big difference

Every time you assemble your razor, metal grinds against metal. Over months and years, that friction dulls the finish and wears down threads. A Delrin washer creates a soft barrier that absorbs the pressure, keeping your razor looking and working like new. It also prevents the handle from over-tightening, which can strip threads or crack the base plate.

When a washer is more than just protection

If your handle isn't tapped deep enough, a thin base plate may not sit flush. A washer fills that gap, letting you tighten the razor securely without wobble. This is common with aftermarket handles or when mixing parts from different razors. The washer ensures a stable, safe shave without damaging any components.

Choosing the right washer

Not all washers are created equal. Delrin (acetal resin) is ideal because it's durable, water-resistant, and won't scratch metal. Avoid metal washers, which defeat the purpose, and rubber ones, which can degrade. Size matters: a 0.34" outer diameter and 0.2" inner diameter fits most standard safety razors. Thickness around 0.053" works well for most setups.

How to install and maintain Delrin washers: step-by-step

1. Disassemble your razor: Unscrew the handle from the razor head. Set the cap and blade aside. Wipe any excess lather or debris from the threads. Checkpoint: Make sure the threads are clean and dry before proceeding.
2. Place the washer on the handle threads: Slide the Delrin washer over the threaded post of the handle. It should sit flat against the handle's top edge. Common mistake: Forcing the washer if it doesn't fit—check that you have the correct size (0.34" OD, 0.2" ID).
3. Reassemble the razor: Place the blade on the cap, then align the base plate and screw the handle (with washer) into the cap. Tighten until snug—do not overtighten. Checkpoint: The washer should be sandwiched between the handle and base plate, not visible from the side.
4. Inspect and adjust: Check that the blade is aligned and the razor is secure. If the handle doesn't tighten fully, the washer may be too thick—try a thinner one or remove it. Common mistake: Overtightening to compensate for a loose fit; this can damage threads.
5. Clean and replace as needed: Rinse the washer with warm water and mild soap. Inspect for wear or deformation every few months. Replace if it becomes compressed or cracked. Next step: Keep spare washers on hand—they're inexpensive and ensure uninterrupted protection.
