An axle assembly can include a housing, differential assembly in the housing, drain plug, cover, and gasket. The housing can include a main flange having threaded bores. A bottom threaded bore can extend through the main flange to be in fluid communication with a housing interior. The plug can include a shaft and a head. The shaft can threadably engage the drain bore. The cover can include a cover flange. The head of the drain plug can overlap the cover flange. The gasket can include a seal portion in sealing contact with the flanges, a standoff, and a fastener seal member. The shaft can extend through the standoff. The standoff can be a rigid material disposed between the flanges and can extend radially outward of the drain bore. The fastener seal member can be a resilient material in sealing contact with the standoff and the drain plug.
