A wear cap (10) for protecting the wearable surface of a structural member includes an outer wear surface and an inner mounting surface (16). The inner mounting surface (16) is provided with a plurality of tabs (36, 38) and a lo ck which cooperate to securely attach the wear cap (10) to the wearable surface . The tabs (36, 38) are inclined in a uniform direction at an acute angle to t he mounting surface (16) to minimize the amount of travel needed to install and remove the wear cap (10). The lock has a rigid hub and a shaft. The hub includes a pair of bearing faces which interact with the wear cap (10) and t he wearable surface (29) to effectively prevent loss of the wear cap (10) durin g use. |
