Abstract
Abstract Disclosed is a lug nut 10 capable of manufacture on existing nut forming machinery having a continuous thread through the entire axially inner surface 12 while having suitable drive means placed upon the axially outer surface 14 such as a conventional hex 16. The lug nut 10 has a conical bottom section 18 for tight engagement and centering of a vehicle wheel upon a vehicle and an integrally formed flange 20 at the other end thereof along with seat 26 for acceptance of an insert 28 in tight engagement therewith. The insert 28 can have a highly reflective surface 32 to provide a safety feature for night time driving.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
152 words
A lug nut comprising: a nut having axially inner and outer surfaces; said axially inner surface having a thread continuously through the entire axially inner surface; said axially outer surface having a suitable driver means; at one end of said axially outer surface, a conical bottom section for tight engagement of a wheel to a vehicle axle hub; at axially the opposite end of said conical bottom section, an integrally formed flange conically sloping toward said axially inner surface having a bore diameter at the small conjugate plane greater than the groove diameter of said thread of said axially inner surface; an insert seat extending from the inner surface of the large conjugate plane of said integrally formed flange to said axially inner surface; and an insert having a flexible slightly conical flange to snap fit into said integrally formed flange so as to • stop upon said seat in tight engagement.
Claim 2
Dependent Claim
152 words
A lug nut comprising: a nut having axially inner and outer surfaces; said axially inner surface having a thread continuously through the entire axially inner surface; said axially outer surface having a suitable driver means; at one end of said axially outer surface, a conical bottom section for tight engagement of a wheel to a vehicle axle hub; at axially the opposite end of said conical bottom section, an integrally formed flange conically sloping toward said axially inner surface having a bore diameter at the small conjugate plane greater than the groove diameter of said thread of said axially inner surface; an insert seat extending from the inner surface of the large conjugate plane of said integrally formed flange to said axially inner surface; and an insert having a flexible slightly conical flange to snap fit into said integrally formed flange so as to • stop upon said seat in tight engagement.
