Fastener Tests

Evaluations of fasteners allow companies to comply with regulations. Fasteners are measured by length and width of the shank, angle and type of the thread, shape and size of the head. And, fasteners are tested for how much force it takes to bend them, and how much force it takes to pull them out after they’ve been driven into any particular substance (wood, metal, plaster, etc…). The more force that it takes to bend or pull the fastener, the stronger that fastener is, which in turn leads to a stronger finished product.

The Morgan Impact Bend Angle Nail Test (MIBANT) evaluates fastener quality to predict the fastener properties while in use. Other fastener tests include the Fastener Quality Analysis (FQA), which provides information about the effectiveness of the investigated fastener on the durability of the pallet.

Fastener tests also provide information about compliance with ANSI Mh1. The FWI (Fastener Withdrawal Index) and FSI (Fastener Shear Index) are calculated as described in ASTM F680. Additional performance evaluations include actual withdrawal/shear/head pull through resistance of nailed joints. These tests follow ASTM D1761.

Package testing and pallet testing are important parts of the research and development process. Testing helps ensure that all new pallet and package designs are created specifically to handle real-world situations.

Standards:

ASTM F680
ASTM D1761
MH1 - Part 6

ASTM F680 – 17: Standard Test Methods for Nails

These test methods cover procedures for the testing of nails. The test or tests selected, and the requirements for compliance, will be as specified in the applicable product standard. Performance tests for nail withdrawal and lateral load capability are not included. The tests described are as follows: Dimensional tests, Tension test, conventional bend test, Impact bend test, Rockwell hardness test, coating weight test, coating adherence test for zinc-coated nails.

ASTM D1761 – 12: Standard Test Methods for Mechanical Fasteners in Wood

This test provides 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. 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.

MH1 – Part 6: Pallets, Slip Sheets, and Other Bases for Unit Loads – Protocol for Measuring Quality of Pallet Nails and Staples.

This standard pertains to pallets used in the unit-load method of assembling, stacking, storing, handling, and transporting materials and products. The standards were to accomplish the following: define terminology and nomenclature associated with pallets; apply to pallets irrespective of components and materials used in their fabrication; provide a series of recommended pallet dimensions and sizes; describe procedures for pallet sampling, inspection, and testing
