These full-thread screws reach ≈ 116 ksi (800 MPa) tensile strength and feature a Zinc-Plated & Baked finish for bright appearance, added corrosion protection, and post-plating bake to relieve hydrogen embrittlement. Perfect for industrial, automotive, and machinery builds requiring flush mounting, high clamp loads, and reliable torque transfer.
Monster Bolts backs every screw with strict quality control, rapid U.S. shipping, and customer-first support, making us the trusted source for professionals and DIYers alike.
