Value Collection 830-3300 Steel Transfer Screw Set 4 Piece

Product Description

The VALUE COLLECTION 830-3300 is a four-piece steel transfer screw set covering four common unified coarse thread sizes: 1/4-20, 5/16-18, 3/8-16, and 7/16-14. Transfer screws are precision-ground, headless tools used to locate and mark hole center points when transferring bolt patterns from one workpiece to another. The set is made from steel for durability under repeated use. It is a standard hand-tool item used by machinists, millwrights, fabricators, and trade mechanics who need accurate bolt-pattern transfers without layout measurement.

This set is suited for general shop and field use where bolt-hole patterns must be transferred to a mating part or surface. Common applications include matching mounting flanges, fabricating brackets, and aligning equipment bases. The four included thread sizes cover the most frequently encountered fastener dimensions in light industrial and mechanical trade work, making this a practical bench tool for any shop that handles equipment installation or repair.

Key Features

• Four-piece set covers 1/4-20, 5/16-18, 3/8-16, and 7/16-14 thread sizes

Compatibility

Designed for use with standard unified coarse (UNC) threaded holes in the 1/4-20, 5/16-18, 3/8-16, and 7/16-14 size range, consistent with common fastener patterns found in general mechanical and fabrication work.

Installation Notes

Transfer screws are hand tools and do not require power tools for use. Thread the appropriate screw into a tapped hole by hand, then press or tap the mating workpiece against the protruding tip to mark the center point. Keep the screw tips protected from damage when not in use to maintain marking accuracy. No electrical shutoff or code compliance is required for use of hand layout tools.
