The GPM SR5OD12TK1 Stainless Steel 5mm Round Head Screw Spacer Set is engineered to provide repeatable spacing and surface protection at screw joints. Manufactured from stainless steel, the spacers deliver corrosion resistance and wear tolerance while forming a hard seating under screw heads to reduce localised compression on plastic and alloy parts. This straightforward upgrade helps preserve chassis geometry and mounting integrity during assembly and regular maintenance.
