## Description

Product Description HEADLOK SCRW 2.875"500PC From the Manufacturer Save time, money, and labor costs. HeadLOK eliminates the need to predrill and hand-ratchet in 3/8 inch galvanized lag screws in wood-to-wood projects. HeadLOK's aggressive threading and sharp gimlet point allows it to zip right into wood or OSB without predrilling. Plus, the wafer head eliminates the need for washers and offers increased pull through strength. Perfect for deck framing, stair stringers, fencing, cabinets, and more! Sizes are perfect for virtually any dimensional wood-to-wood project. HeadLOK fasteners are American made.

Review: Fantastic screw - highly recommeneded - I used these to attach my band of my new deck in a uniform way. It pulls the wood in tight and looks great instead of the unsightly nail/screw holes. I also used the 5 1/2 to attach my post for my railing. The screws are very durable and the bits are non slip - made for the impact drill. It's a must have for outdoor projects. This is the 3rd time I've used these and will definitely continue.
Review: Awesome screws for construction. - These screws are awesome. They are much stronger than deck screws. They are much faster to install than lag or carriage screws and look even better. The large flat head provides much more holding power without the need for washers and still keeps a low and smooth profile. I used them for wooden railing on my bridge and they look great against the stained wood. When installing any of these spider drive screws you need to apply lots of pressure to keep the bit well engaged especially on the longer screws that take more power. You will wear the tips out and need to use more than one to complete a bucket.

## Features

- Nationally code compliant stronger design shear values than 3/8 inch lag screws

### ⭐⭐⭐⭐⭐ Do what you’d expect
*by E***Z on June 6, 2025*

These screws are perfect for mating two 2x’s together. They are just the right length so that they will not show through on the other side. Price is reasonable for the amount of screws you get. Screws hold up well. I have never broken one. They are easy to drive and come with a special star drive bit that only fits these screws. The screw head is large preventing the screw to get over driving into the wood. I wish the thread was a bit more aggressive but it works.
