Double-head transfer screw bolts (Doppelkopf-Transferschraubenbolzen) Key benefits Durable, reusable fastener for joining or aligning components where two thread sizes or lengths are needed. Simplifies assembly and repairs by combining two fastening functions in one part, reducing part count and installation time. Designed for precise engagement to maintain alignment and reliable mechanical connection. Main features Size: Size = M1 * L1 – M2 * L2 (select the required M and L values when ordering). Material: Made from high-quality Stainless Steel 304 for long service life and repeated use. Quantity options: Available as 1 piece, 2 pieces, or 5 pieces per order. Item: Double-head transfer screw bolts (Doppelkopf-Transferschraubenbolzen). Function and compatibility Two-head design accommodates two different thread/length combinations (M1/L1 on one end, M2/L2 on the other) so one bolt can connect or transfer threads between matched parts. Use where components require different thread sizes or where a transfer fastener must engage two mating parts with distinct depths. Ensure chosen M and L values match the mating threads and component thicknesses for correct fit. Typical applications Furniture and cabinetry: join panels or attach fittings where one part needs a shallow thread and the other a deeper engagement. Appliances and equipment assembly: secure internal components that require different thread engagements without additional adapters. Repair and prototyping: replace worn or missing transfer bolts to restore mechanical alignment and fastening integrity. Ordering and installation tips Confirm the exact size specification before ordering: Size = M1 * L1 – M2 * L2. Choose the appropriate quantity option (1, 2, or 5 pieces). Match the bolt ends to the corresponding threaded holes; tighten to recommended torque for the materials involved to avoid damage.
