Standard Test Methods for Mechanical Fasteners in Wood
SCOPE
1.1 These test methods provide a basic procedure for evaluating the resistance of wood and wood-base materials to direct withdrawal of nails, staples, and screws. Spikes are included as nails in this standard.
1.2 The tests also provide a basis for determining comparable performance of different types and sizes of nails, staples, and screws in direct withdrawal from wood and wood-base materials.
1.3 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

INTRODUCTION
The use of wood and wood-base materials in many structural and other applications often involves
the use of mechanical fasteners, such as nails, screws, bolts, lag screws, and connectors. Data on the
strength and performance of such fasteners are frequently needed for design and for comparative
purposes. Tests of mechanical fasteners (except nail withdrawal) have been generally regarded as
special tests and have not been included in the standard methods already established for evaluating the
properties of wood. Many such special tests have been extensively used over a considerable period but
have not previously been established as standards. Presented herewith are methods of conducting tests
for nail, staple, and screw (except machine screws) withdrawal resistance; lateral load transmission by
nail, staple, screw, bolt, and timber connector; and load transmission by nail plates and joist hangers.
The use of standard methods for these tests is recommended as a means of obtaining comparable data
and of eliminating variables in test results because of variations in testing methods.
The tests appear in the following order:
Sections
Nail, Staple, or Screw Withdrawal Test 1to12
Lateral Nail, Staple, or Screw Resistance Test 13 to 20
Testing Bolted and Timber Connector Joints 21 to 30
Tension Tests of Plate-Type Connector Joints 31 to 40
Joist Hanger Tests 41 to 50
Precision and Bias 51
