Hex nut for string trimmer head
I had a very daunting task of locating a left hand metric thread hex nut to secure my string trimmer head. After many web searches and interviews, I located this company and they gave me exactly what I needed and were very pleasant to deal with as a new customer. I would definitely recommend this firm to anyone faced with a challenging landscaping equipment application.

Not same as original
I remember the original being a castellated nut, so that the cotter pin locks the nut in place to hold the brush blade in.. nut is also on the short side and seats will below the cotter pin hole, might need to add a washer to take up the space, will need to tighten with a socket, not an open end wrench as the top of the nut is almost flush with the Fixture-Blade Part Number: C535000150
