Shoulder Screw Shims

Shoulder screw shims provide defined spacing adjustments for shoulder-screw assemblies in tooling, maintenance, die work, and assembly applications. Lengthening shims install over stripper screw threads beneath the shoulder to increase effective screw length, while shortening shims install beneath the screw head to shorten the effective shoulder length for a closer assembly fit.

Helpful Buying Guide

Choose Shoulder Screw Shims for the Required Adjustment

Compare shoulder screw shims first by whether the application calls for lengthening or shortening, then match the shim to the compatible shoulder screw diameter and required thickness. The available options include metric and inch-based screw fits, defined thickness increments, stainless steel and spring steel constructions, and 25- or 50-piece packs.

Use Cases

Adjust effective screw or shoulder length

Use lengthening shims beneath the shoulder to increase effective stripper screw length. Use shortening shims beneath the screw head to shorten the effective shoulder length.

How to Choose

Planning Guide

Plan the right fit before choosing

Select the shim function

Decide whether the assembly needs lengthening or shortening

The installation location distinguishes the two shim types. Lengthening shims fit over stripper screw threads beneath the shoulder. Shortening shims fit beneath the screw head and are described with precision die-cut openings or profiles that fit closely around the shoulder screw shank.

  • Choose lengthening shims to increase effective stripper screw length.
  • Choose shortening shims to shorten effective shoulder length.
  • Confirm the intended installation location before selecting a shim.
Match the screw and spacing

Use the stated screw fit and thickness

The represented range includes shims for 6 mm, 8 mm, 10 mm, and 16 mm shoulder screws, along with options for 3/8 in. and 1/2 in. shoulder screws. Listed thicknesses include 0.25 mm, 0.40 mm, 0.50 mm, and 0.80 mm, plus 0.005 in., 0.015 in., and 0.032 in. options.

  • Match the shim to the compatible shoulder screw diameter.
  • Select the defined thickness increment needed for the adjustment.
  • Review stated ID and OD dimensions where they are provided.
Plan for ongoing work

Consider material and quantity needs

Stainless steel options are specified as 302 or 302 full-hard stainless steel. Spring steel options include tempered spring steel, 1095 spring steel, and 1075 tempered spring steel. Packs of 25 support installation, replacement, assembly, or maintenance needs, while 50-count packs are represented for repeated setup and tooling adjustments.

  • Choose from stainless steel or specified spring steel constructions.
  • Use 25-piece packs for multiple shim needs.
  • Consider 50-piece packs for ongoing tooling adjustments.
