Hex Head Wood Screws: Sizes, Types, Uses, and Modern Options

When it comes to con­struc­tion and DIY projects, select­ing the right fas­ten­ers is cru­cial. Among the many options avail­able, hex head wood screws are a reli­able choice. They are durable, easy to use, and strong, which makes them pop­u­lar among pro­fes­sion­al builders, con­trac­tors, and seri­ous DIY enthusiasts. 

This arti­cle explores the world of hex head wood screws by cov­er­ing their sizes, types, and uses, and show­cas­ing the spe­cial­ized prod­ucts offered by Fas­ten­Mas­ter, a leader in the fas­ten­er industry.

Understanding Hex Head Wood Screws

What Are Hex Head Wood Screws?

Hex head wood screws are char­ac­ter­ized by a hexag­o­nal head usu­al­ly dri­ven with a stan­dard drill or impact dri­ver. This smart design offers a larg­er sur­face area that pre­vents the head from sink­ing into the mate­r­i­al. These screws are com­mon­ly made from durable mate­ri­als like steel, stain­less steel, or brass, and may fea­ture pro­tec­tive coat­ings such as zinc or black oxide to enhance their cor­ro­sion resistance.

Key Features of Hex Head Wood Screws

Design Advantages

The hex head design offers sev­er­al advan­tages over oth­er screw types. The shape allows for a more secure grip to reduce the risk of strip­ping, which makes it eas­i­er to dri­ve into wood. This design is par­tic­u­lar­ly ben­e­fi­cial in appli­ca­tions where high torque is required.

Durability and Strength

Uti­liz­ing hex head screws is a fan­tas­tic way to best ben­e­fit from the strength and dura­bil­i­ty of the screw shafts them­selves. The mate­ri­als and man­u­fac­tur­ing process­es used in mak­ing them help to ensure that they can with­stand harsh con­di­tions, includ­ing out­door envi­ron­ments. The secure grip of the hex head makes sure that the full strength of the screw shaft is appro­pri­ate­ly fastened.

Practical Applications in Building and DIY Projects

Versatility in Use

Hex head wood screws are ver­sa­tile and they can be used in a wide range of projects. From build­ing decks to con­struct­ing fur­ni­ture, they pro­vide the strength and reli­a­bil­i­ty need­ed for both pro­fes­sion­al and per­son­al projects.

Tips for Selecting the Right Screw

Choos­ing the right hex head wood screw for your project is crit­i­cal. Con­sid­er the type of wood, the envi­ron­men­tal con­di­tions, and the load the screw will need to sup­port. Con­sult­ing a size chart can also help you make the right choice.

FastenMaster’s Specialized Products

Stan­dard hex head wood screws, while ver­sa­tile and durable, may not be suit­able for more robust appli­ca­tions where struc­tur­al integri­ty is a crit­i­cal require­ment. They may lack the nec­es­sary strength or cor­ro­sion resis­tance need­ed when deal­ing with high load-bear­ing projects or severe weath­er conditions.

This is where Fas­ten­Mas­ter’s spe­cial­ized prod­ucts, such as Ledger­LOK, Tim­ber­LOK, and Thru­LOK, are a supe­ri­or alternative.


LedgerLOK® Flat Head Wood structural deck screws

Ledger­LOK is the first wood screw specif­i­cal­ly designed for attach­ing decks to hous­es, that offers enhanced strength and resis­tance. With a built-in wash­er head, there is no need for an addi­tion­al wash­er, which pro­vides a stronger con­nec­tion and reduces instal­la­tion time and cost.

Key Benefits

Stronger Hold

Ledger­LOK screws are designed specif­i­cal­ly for ledger boards and they have an incred­i­bly stronger hold than stan­dard screws. They are engi­neered to ensure the secure attach­ment of the ledger to the house framing.

Higher Resistance

Ledger­LOK’s coat­ing enhances their resis­tance to cor­ro­sion which makes them ide­al for out­door applications.

Faster Installation

With no pre-drilling required, Ledger­LOK screws reduce instal­la­tion time for increased pro­duc­tiv­i­ty on the job site.

Ideal Application

Deck Building

Ledger­LOK screws pro­vide a secure and last­ing fas­ten­ing solu­tion for attach­ing the deck­’s ledger board to the house.


Tim­ber­LOK structural deck screws

Tim­ber­LOK is anoth­er rev­o­lu­tion­ary prod­uct from Fas­ten­Mas­ter that has sev­er­al advan­tages over stan­dard hex head wood screws.

Key Benefits

Superior Penetration

With its sharp point and aggres­sive thread, Tim­ber­LOK ensures deep pen­e­tra­tion and a strong bond with­in the wood.

Enhanced Durability

The high qual­i­ty of the met­al and the unique coat­ing ensures excel­lent cor­ro­sion resis­tance which makes Tim­ber­LOK screws per­fect for out­door use.

No Pre-Drilling Required

Just like Ledger­LOK, Tim­ber­LOK screws also elim­i­nate the need for pre-drilling, to save time and effort dur­ing installation.

Code Compliant

Tim­ber­LOK meets ICC-ES ESR-1078 and 2020 IRC and IBC code require­ments, to help ensure safe­ty and reliability.

Ideal Applications

Landscape Timbers

Their cor­ro­sion resis­tance makes Tim­ber­LOK screws an excel­lent choice for con­struct­ing out­door land­scape fea­tures like retain­ing walls.

Rafters and Trusses

The strength of Tim­ber­LOK screws ensures a secure and last­ing con­nec­tion with­in roof structures.


Thru­LOK is Fas­ten­Mas­ter’s ver­sa­tile fas­ten­ing solu­tion that excels beyond the capa­bil­i­ties of stan­dard hex head wood screws.

Key Ben­e­fits

Streamlined Installation

Thru­LOK’s three-part assem­bly includes a screw, nut, and wash­er, to elim­i­nate the need to fum­ble with loose parts. This design sim­pli­fies and accel­er­ates the instal­la­tion process.

No Pre-Drilling Required

Thru­LOK saves time by elim­i­nat­ing the need for pre-drilling, to speed up project com­ple­tion times.

Superior Length

With lengths up to 9−1÷2”, Thru­LOK has solu­tions for appli­ca­tions requir­ing longer fasteners.

Code Compliant

Just like Tim­ber­LOK, Thru­LOK is also code-com­pli­ant, which demon­strates its reli­a­bil­i­ty and safe­ty in con­struc­tion applications.

Ideal Applications

Deck Posts

One of the best appli­ca­tions for Thru­LOK is deck posts. While per­fec­tion in con­struc­tion is crit­i­cal to suc­cess, it’s absolute­ly imper­a­tive to get it right with your foun­da­tion. Thru­LOK makes sure you’re get­ting the best con­nec­tion for your deck’s foun­da­tion after sink­ing the posts.

Carrying Beams

Due to their supe­ri­or length and strength, Thru­LOK screws are ide­al for fas­ten­ing car­ry­ing beams in deck and porch construction.
