// PART IDENTIFICATION

Identify the regular helical-spring family

MS35338 covers regular, or medium-series, helical spring lock washers. Their split spring form differs from flat washers and internal- or external-tooth lock washers.

The required washer style and material belong in the callout; the mating screw size alone does not identify an alternate.

// PART-NUMBER EXAMPLES

Size and material share the dash-number table

MS35338-40 and MS35338-135 both reference a #4 screw size, but identify different material groups. The selected -39 through -42 entries are plated carbon steel; the selected -134 through -141 entries are passivated corrosion-resistant steel.

MS35338-96 is a #2 phosphor-bronze or tin-brass selection. It should not be grouped with the carbon-steel entries.

// DRAWING CHECK

Confirm the coating and section dimensions

A plated-carbon-steel reference does not resolve every coating requirement. Preserve the coating called out by the drawing and applicable standard issue.

The screw-size reference is not the measured hole diameter. Confirm the required inside diameter, outside envelope and washer section against the drawing before proposing an alternate.
