“I am in no way a stranger to Toolcraft bolts, a good hardy bolt the performs like promised or better. I purchase mostly melonited bolts, and I have been very pleased with them, but the DLC coated bolts!! Whoa!! Toolcraft pushed the envelope with this one hard coated bolt! Hard to scratch or mar, no need to tip toe around with this bolt and as always I rely on Arm or Ally to purchase my project needs. Two top notch companies.”
