Product description

Specification: Specifications Meet ASME/ANSI B18.2.1-15-2012 Height of the Head: 0.235 inch Thread Size: 5/16 inch External Hex Drive: 1/2 inch Thread Pitch: 9 TPI Color: Silver Tone About Hex Head Lag Bolts Hex head lag screws are coarse thread screws requiring a pre-drilled hole with minimal clearance above the fastener to prevent splitting or snappin. Lag screws are some of the toughest screws. Six sided head design makes it ideal for easy and quick installation with a hex drive and could tightened with more torque than phillips head machine screws. Lag screws are deal used for securing wood in heavy duty applications like deck building that standard wood screws cannot support the load. They're often combined with washer to evenly distribute the pressure of the head as well as preventing pull through. At the same time, they could work independently without a nut. Use this lag screw to attach objects to wood or anchor masonry. Common applications include retaining walls, deck frames, and outdoor play equipment. For masonry application, use the screw in conjunction with a lag shield. The high quality 304 stainless steel provide perfect strength and good corrosion resistance in bad environments like high temperature, cold weather and high humidity areas without the need for time consuming and costly maintenance.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.
