These 100-piece assorted plastic packers are small, non-metallic shims used to level, space and align components during installation and assembly. Made from injection-moulded nylon (polyamide), the packers provide consistent, thin, non-conductive gaps between materials — their primary use is to take up tolerance, prevent rattles and ensure even bearing in glazing, window and door fitting, furniture assembly, electrical installations and light mechanical alignments.

The packers are manufactured from Nylon (polyamide) with a natural moulded finish, offering a balance of stiffness and resilience typical of PA6-grade materials. As simple solid shims they have no thread, head or drive type; instead they are supplied as flat or tapered washer-style and rectangular shims in a selection of thicknesses. Plastic packers are not governed by DIN/ISO fastener head or thread standards, but the base polymer conforms to general polymer test standards and can be assessed to ISO 527 (tensile) and ISO 178 (flexural) on request.

Typical applications include levelling window frames and doors during installation, spacing timbers and panels to allow for expansion, insulating electrical terminals where non-conductive isolation is needed, and spacing hinges, brackets and panels in furniture and shopfitting. Industries that commonly use these packers are construction and glazing, joinery and cabinet making, electrical contracting, telecommunications equipment mounting and general maintenance workshops where rapid, repeatable shimming is required.

Key benefits include intrinsic corrosion resistance since nylon does not rust or oxidise, electrical insulation for safe use around live systems, low weight for ease of handling and storage, and good compressive strength for light to medium duty packing. The material’s compatibility with common fastening methods means packers sit comfortably under screws, bolts or adhesive joints without reacting with timber, metals or most surface finishes. They are not intended as primary structural fasteners for heavy loads.

Duchy Fasteners stocks this 100-piece assortment in a range of common thicknesses and profiles to suit glazing, joinery and electrical work. Packs are supplied with multiple shim sizes so you can select the right thickness on site; larger or single-size packs are available on request.
