these be excellent medium duty work glove ! soft and flexible enough to handle screw and bolt with out a problem , yet strong and durable leather palm and extra leather pad in the right area to protect you hand . the velcro on the elastic wrist band keep the glove in place . they fit like a second skin . the leather palm would provide some low heat protection , but the back be weave plastic so do not try welding with they . I personally wear these glove most of the time while I be work . do not just buy one pair ... but two or three !
