Question 1

Define blind hole.

Accepted Answer

A blind hole is a hole that does not go through.

Question 2

Name the device, usually threaded, that displaces the material around a mounting hole when pressed into a properly sized drilled or punched hole. This pressing or squeezing process causes the displaced sheet material to cold flow into a specially designed annular recess in the shank or pilot of the fastener. A serrated clinching ring, knurl, ribs, or hex head prevents the fastener from rotating in the metal when tightening torque is applied to the mating screw or nut.

Accepted Answer

A self-clinching fastener.

Question 3

List and describe the components of this thread note by specifying A through D: M 10 X 1.5-6H [M=A, 10=B, 1.5=C, 6H=D].

Accepted Answer

A = M is the symbol for ISO metric threads and is always placed in this location.
B = The nominal major diameter in millimeters, followed by the symbol X, meaning by.
C= The thread pitch in millimeters, followed by a dash (-).
D = The number can be a 3, 4, 5, 6, 7, 8, or 9, which identifies the grade of tolerance from fine to coarse. The larger the number, the larger the tolerance. Grades 3 through 5 are fine, and 7 through 9 are coarse. Grade 3 is very fine and grade 9 is very coarse. Grade 6 is the most commonly used and is the medium tolerance metric thread. The grade 6 metric thread is comparable to the class 2 Unified screw thread. A letter placed after the number gives the thread tolerance class of the internal or external thread. Internal threads are designated by uppercase letters such as G or H, where G means a tight allowance and H identifies an internal thread with no allowance.
