Overview
The Wiha 77891 is a single-piece nut driver priced at $14.37. Wiha is one of the more recognized names in nut drivers, and the 77891 carries a 4.7-star rating from 1,289 verified reviews with 200 monthly buyers, a solid performance for a single-piece listing.
The published specs do not include a length or weight measurement for the 77891. Buyers familiar with Wiha's broader driver line will associate the brand with consistent build quality, but without dimensional data in the listing, head-to-head reach comparisons with the 6-inch Malco MSHXLC or ABN 5062 cannot be made from specs alone.
At $14.37, the Wiha 77891 positions between budget single-piece options under $10 and the premium $19 to $20 Malco single drivers. For buyers who want Wiha quality in a single driver for a specific application, the rating and price represent a fair value for those comfortable with the missing dimensional data.
