Standard Test Methods for Mechanical Fasteners in Wood

SIGNIFICANCE AND USE
4.1 The resistance of a species of wood or a wood-base product to direct withdrawal of nails, staples, or screws is a measure of its ability to hold or be held to an adjoining object by means of such fasteners. Factors that affect this withdrawal resistance include the physical and mechanical properties of the wood; the size, shape, and surface condition of the fasteners; the speed of withdrawal; physical changes to wood or fasteners between time of driving and time of withdrawal; orientation of fiber axis; and the occurrence and nature of prebored lead holes.  
4.2 By using a standard size and type of nail, staple, or screw, withdrawal resistance of a wood species or wood product can be determined, and such values for two or more wood species or wood products can be compared. Throughout the method this is referred to as the basic withdrawal test. Similarly, comparative performances of different sizes or types of nail, staple, or screw can be determined by using a standard procedure with a particular wood or wood product, which eliminates the wood or the wood product as a variable. Since differences in test methods can have considerable influence on results, it is important that a standard procedure be specified and adhered to, if test values are to be related to other test results.
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.

original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A

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
propertiesofwood.Manysuchspecialtestshavebeenextensivelyusedoveraconsiderableperiodbut
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. 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:

Nail, Staple, or Screw Withdrawal Test 1 to 12
Lateral Nail, Staple, or Screw Resistance Test 13 to 20

3.1 Specimens consist of prisms of wood or wood-base
products, with nails, staples, or screws driven at right angles to
one or more faces. The fasteners are withdrawn at a uniform
rate of speed by means of a testing machine, and the maximum
load is recorded. Supplementary physical properties of the
wood or wood-base product are also determined.
