Die Life Replacement Washer & Screw Kit for Stock Lifters - Inch

This die life replacement washer & screw kit is used to service progressive and production injection mold tooling where stock lifters must cycle reliably over long runs. The washer and screw hardware helps restore clamping consistency after wear, supporting stable movement and preventing performance drift during repeated actuation.

Common scenarios include:

• Automotive connector molds: rebuilding stock lifters that index precisely for small, repeatable features; refreshed fasteners help maintain consistent lifter operation under production load.
• Consumer/industrial housings: maintaining heavy duty lifters in high-throughput dies where hardware fatigue can lead to uneven travel or unreliable actuation.
• High-cavitation progressive tooling: replacing worn components in inch stock lifter configurations to extend die service intervals.

Because this variant is specified for inch lifter models (Model 75, Model 112, Model T-750) and includes compatible washer thickness options, it is suited for rebuilds that require matching the original lifter geometry and travel behavior.

This kit uses a steel construction designed for dependable fastening under cyclic mechanical load. In mold build and maintenance work, steel replacement hardware is selected to retain dimensional stability and resist loosening when lifters undergo repeated compression and return strokes.

• Hardness / wear-toughness balance: the specification provided identifies the material as steel, but does not state a target HRC. For rebuild planning, treat the hardware as wear-critical and verify that the supplied lot meets your internal torque and fatigue requirements.
• Heat treatment: no heat-treatment condition (e.g., quenched & tempered, nitrided) is listed in the provided data; confirm the as-supplied condition if you require known surface hardness for fretting resistance.
• Trade-offs: steel typically offers a strong balance of toughness and wear resistance compared with softer fastening options, helping reduce the risk of gradual hardware degradation during long production cycles.

Select dimensions by matching the washer/screw kit to the stock lifter geometry and the lifter configuration in your mold. Use the provided ranges to ensure the replacement hardware aligns with the lifter’s required travel and interface.

• Length (in): choose a kit length within 2.312 ~ 7.562 in.
• Thickness (in): select 0.187 in or 0.250 in based on your existing washer stack-up and clearance.
• A Travel (in): confirm the kit matches one of the listed values: 0.50, 0.75, 1.00, 1.25, 1.50, or 1.75 in.
• Stock lifter O.D. (in): ensure compatibility with 0.7495 in or 1.1245 in configurations, including tolerance guidance where shown (for 0.7495 in: +.0000 / -.0015).

For Model selection, use the provided Model 75, Model 112, or Model T-750 to align the replacement hardware with the correct inch lifter design and rebuild procedure.
