ASTM D1761-06

Standard Test Methods for Mechanical Fasteners in Wood

SIGNIFICANCE AND USE
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.
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.
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.
1.3 This test method covers the determination of the resistance to lateral movement offered by a single nail, staple, or screw in wood members. The test provides comparative data for various species of wood. This general test method can also be used for evaluating other types and sizes of fastenings either in wood or other building materials such as plywood, hardboard, etc., or combinations of materials. Furthermore, where required for specific purposes, the general method can be used for evaluating the lateral resistance of sizes of nails, staples, and screws other than those specified, and joints employing two or more fasteners. It is recommended that when such tests are made, the specified procedure be followed as closely as possible and all deviations be completely described.
1.4 This test method provides a suitable procedure for evaluating the strength and rigidity of timber joints fastened with bolts or with metal connectors which usually also require bolts to form the joint. The test serves as a basis for developing design criteria and for determining the effect of various factors on the strength and efficiency of the joint.
1.5 This test method covers determination of the tensile strength and stiffness characteristics of symmetrical joints in which parallel planar wood members are connected by fasteners of the type commonly known as "truss plates." This method has been especially designed for determining the tensile properties of joints that connect nominal 2-in. dimension lumber such as those commonly used in light roof truss assemblies. It is recommended that the specified procedure be followed as closely as is practicable and that any deviations be described.

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:
