Log Boss Timber Screws
Maximum Strength Log & Timber Fasteners – Engineered for Performance
What Makes Log Boss Timber Screws Unique?
Log Boss Timber Screws are structural fasteners specifically built for log and heavy timber construction. These screws feature an aggressive 3-inch thread that provides superior holding power, while the smooth upper shank allows for natural log settling—an essential feature for log home builds. The redesigned hex head and reintroduced wings ensure low driving torque, clean countersinking, and no need for washers or pre-drilling. Whether you’re assembling log walls or installing landscape timbers, Log Boss provides the strength and ease of installation professionals demand.

Frequently Asked Questions
Do Log Boss screws require washers?
No. The head is engineered to create strong pull-down force without the need for washers, reducing installation time and materials.
Is pre-drilling necessary?
No. Log Boss screws are designed for direct drive-in without pre-drilling, even into dense timbers. The wings clear debris and reduce installation torque.
How do Log Boss screws compare to TimberLOK or LogHog?
Independent tests show that Log Boss screws have significantly higher tensile and shear strengths. They also include a full 3″ thread for better pull and a smooth shank for settling—features not found on all competitor fasteners.
Can these screws be used in treated wood?
Yes. The corrosion-resistant coating makes them suitable for use in treated and exterior-grade wood, including landscape and structural timbers.
What tool should I use to install Log Boss?
Use a 1/2” drill with low RPM and high torque, ideally around 450 RPM, with a 5/16” hex driver bit.
Do the screws allow for log settling?
Yes. The smooth portion above the 3” threaded section is specifically designed to accommodate natural log and timber movement after installation.
Are Log Boss screws rated for structural use?
Yes. They are tested to meet and exceed structural fastening standards for wood-to-wood applications, including high-load-bearing joints.
What lengths are available?
Log Boss screws are available in lengths ranging from 4 inches up to 16 inches to accommodate a wide range of structural needs.
Do these screws countersink cleanly?
Yes. The redesigned hex head ensures a flush finish without damaging the surface of the wood.
Where are Log Boss screws made?
Log Boss screws are manufactured in North America and meet high-performance standards for durability and strength.

Emseal offers 2 Types of Log Home Gasket Tapes:
CLASSIC: For more than 30 years EMSEAL has offered an economical, expanding, open-cell, foam tape impregnated with water-based, acrylic-modified asphalt. Classic Log Home Gasket Tape provides UV stability and sealing ability, as well as resistance to aging and to vermin (bugs, rodents, birds, etc.).
ACRYLIC: EMSEAL Acrylic Log Home Gasket Tape was developed in the early 1980’s using in place of asphalt, a water-based, acrylic impregnation. Compatible with liquid sealants, chinking, and stains and preservatives, it is clean-handling and free from visible contact staining.
EMSEAL Acrylic Log Home Gasket Tape is particularly suitable for construction methods such as Swedish cope and is widely used by handcrafters. It is also suitable for flat-on-flat construction where sealant tape is installed at the outer edges of the logs AND where sprayed-on log sealer or stain may come in contact with the tape.
