Customer Reviews (4.6 / 5 · 5 reviews)

Sofia ★★★★★

Used these to rebuild a tiller tine mount and the Grade 5 steel took all the hammering without stripping. The yellow zinc finish matched the old hardware perfectly and hasn't shown any rust after a month of outdoor use.

Olivia W. ★★★★★

The partially threaded design made all the difference seating these in my equipment frame—no wrestling with thread interference. Yellow zinc finish looks clean and the grade 5 steel feels solid under the wrench. Exactly the length I needed.

Scarlett ★★★★★

Yellow zinc finish looks clean and the partial threading made them sit just right in my fixture build—no binding at all. Wrench grip on the hex head was solid, and the 4-28 pitch held torque without stripping. Exactly what I needed for the job.
