Value Collection 830-3123 Transfer Screw Set 1/4-28 7 Piece

Product Description

The VALUE COLLECTION 830-3123 is a 7-piece transfer screw set designed to locate and transfer hole positions from one workpiece to another with precision. The set includes six 1/4-28 threaded steel transfer screws and one holder, giving machinists and toolmakers a complete solution for layout and drilling operations. Transfer screws seat into existing threaded holes and leave a center-punch impression on a mating surface when pressed together, eliminating the need for separate marking steps. The steel construction provides adequate hardness for use on softer workpiece materials including aluminum, brass, and plastic.

Transfer screw sets are standard toolroom and machine shop consumables used in manual machining, jig and fixture building, and prototype fabrication. The 1/4-28 unified fine thread designation makes this set appropriate for applications where fine-thread fastener holes need to be transferred or matched. The included holder keeps screws organized and allows controlled positioning during the transfer operation. This set is suited for use by machinists, tool and die makers, and maintenance technicians working on precision assembly or fixture alignment tasks.

Key Features

• 7-piece set includes 6 transfer screws and 1 holder for complete transfer operations
• 1/4-28 unified fine thread for compatibility with fine-thread tapped holes
• Steel construction for durability across repeated use on softer workpiece materials
• Holder included for organized storage and controlled screw placement during use
• Compact set weight of 0.15 pounds keeps toolbox footprint minimal

Compatibility

Designed for use in any application requiring transfer of 1/4-28 threaded hole locations, including jig and fixture building, toolroom layout work, and precision assembly operations.

Installation Notes

Transfer screws are installed by a machinist or toolmaker using the included holder to seat each screw into an existing tapped hole. The mating workpiece is then pressed firmly against the screw tips to mark center points for subsequent drilling or reaming. No power tools are required for the transfer operation itself. Ensure workpiece surfaces are clean and free of chips before performing the transfer to maintain location accuracy.
