For replacement work on older equipment, 7/8-9 x 5 keeps the UNC pitch patch, length, and square-head drive clear in the product record.

Typical applications include farm implements, mill equipment, and production machinery that need wrench clearance. The product record carries the size; the requested point is selected from the Half Dog, Full Dog, Cone, Oval, and Flat menu. Point selection should reflect the shaft feature, acceptable marking, and expected service adjustment.

Cold Headers keeps the record focused on usable engineering details so buyers can compare the callout against drawings and service notes. Review the selected point, wrench clearance, and mating feature before substitution. Oval points suit grooves or repeated adjustment where a radiused contact is useful.
