Value Collection 830-3302 Transfer Screw Set 4 Piece Steel

Product Description

The VALUE COLLECTION 830-3302 is a four-piece steel transfer screw set covering four common unified coarse thread sizes: 1/2-13, 9/16-12, 5/8-11, and 3/4-10. Transfer screws are used to locate and transfer hole center points from one workpiece to a mating part, making them a standard layout and fitting tool in machine shops, maintenance shops, and fabrication environments. The hardened steel construction holds up to repeated use across cast iron, aluminum, and steel workpieces. This set gives a machinist or millwright the four most frequently needed UNC sizes in a single package, reducing setup time when fitting bolted assemblies.

This set is suited for general metalworking and mechanical assembly tasks where accurate hole transfer is required. Typical applications include transferring bolt-hole patterns from flanges, brackets, or housings to mating components prior to drilling. The four included sizes cover a wide range of standard fastener applications found in industrial maintenance, HVAC equipment frames, pump and compressor housings, and structural steel assemblies. The set ships as a single package quantity of one.

Key Features

• Four-piece set covering 1/2-13, 9/16-12, 5/8-11, and 3/4-10 UNC thread sizes
• Steel construction for durability across repeated use on metal workpieces
• Transfers hole center locations accurately without measuring instruments
• Compact set format keeps all common UNC transfer screw sizes together
• Single package quantity — no minimum multi-pack requirement

Compatibility

Designed for use with standard unified coarse thread (UNC) tapped holes in the 1/2-13, 9/16-12, 5/8-11, and 3/4-10 size range, compatible with any workpiece that accepts these thread sizes.

Installation Notes

Transfer screws are a layout tool, not a permanent fastener — they are threaded into a tapped hole, a mating part is pressed against the exposed points, and the resulting marks indicate drill center locations. No power tools are required for normal use; a tap wrench or fingers are sufficient to seat the screws. Secure the workpiece before applying pressure to prevent movement during transfer. Follow shop safety practices and wear eye protection when working with metal layout tools.
