Guard4U Socket Head Screws Editorial Review
The Guard4U 300 piece assortment kit including #2-56 UNC stainless steel button head hex socket cap bolts screws and nuts is a great value set with a handy case and a variety of different lengths included. Although some customers have reported that the Allen socket head can be easily stripped, overall the reception to this product has been positive with customers commending the assortment of parts included and the stainless steel quality. However, one customer did mention that the socket on the screws slips easily and causes the screw to become useless.
