Now coming with 400+ screws needed for the HPI Baja 5b RTR and the SS kit. Our screws are made of the highest quality black oxide alloy steel (grade 12.9 metric & grade 8 standard). Today's R/C vehicles demand the strongest materials on the market. Stainless steel screws look nice and resist rust, but they just can't withstand the abuse we are putting on them. No one wants a DNF (did not finish) because they broke a cheap screw. Nor do they want to replace their screws every time they take apart their car because the screw heads strip. All of Tony's Screws come packaged in a reusable zip-lock bag. The header tag fits neatly into the bag sideways so you can quickly identify your hardware. Our Screw Kits also come individually packaged and labeled. You don't have to go digging through a plastic case to find the size you need. HPI Baja 5B 408-piece high grade alloy steel socket head screw kit. Kit includes all applicable caps, flat and button head screws, as well as nuts, washers, lock washers and set screws.
