SD Connector SS Screw

SD Connector SS Screw

The stainless steel Strong-Drive SD Connector hex screw gives you control and reliability where it matters most. Built to last in tough conditions, it’s the fastener professionals trust to get the job done right every time.

Key Features

  • Type 316 stainless steel for maximum corrosion protection.
  • No predrilling necessary in most applications.
  • Driver bit included (replacement driver bit — BITHEXR516-R1 or BITHEXR12-R1).
  • Can be used in ledger applications.
  • Unique “box” thread design with raised-ridge technology significantly reduces driving torque .
  • Hex-washer head provides large bearing area.

Applications

  • Structural wood-to-wood and engineered-wood connections, including ledger.

Product Info

The stainless-steel Strong-Drive® SD Connector SS screw (SD SS) is engineered to replace nails in specific Simpson Strong-Tie® stainless-steel connectors.

Tested and approved for load performance, this screw delivers superior single-fastener load values that exceed those of 10d common nails. Made from Type 316 stainless steel, it offers exceptional corrosion resistance for use in severe-exposure conditions.

The SD SS provides an easier, more controlled installation compared to nails, making it the ideal choice for professionals who value both efficiency and long-term reliability in high corrosion environments.

Technical Specs

Allowable Shear Loads for Wood Connections

1.Allowable loads are shown at the wood load duration factor of CD = 1.00. Loads may be increased for load duration per the building code up to a CD = 1.60.

2. The 15/32" and 23/32" side members must be plywood or OSB with minimum equivalent specific gravities of 0.50 for DFL and SP design values, and 0.42 for SPF and HF design values. See NDS, Table 12.3.3B for specific WSP grades and associated equivalent specific gravities.

3. Loads are based on connections with main members of DFL/SP or SPF/HF and side members as shown and described in table note 2. Screws shall be installed normal to the surface of the wood members.

4. For minimum fastener spacing requirements for both side and main members, see the Spacing Requirements Figure and Table below.

Allowable Withdrawal Loads

Table showing allowable withdrawal loads for DFL and SPF members.

1. The tabulated reference allowable withdrawal value, W, is in pounds per inch of the thread penetration into the side grain of the main member.

2. Tabulated reference allowable withdrawal value, W, must be multiplied by all applicable adjustment factors from the NDS as referenced in the IBC or IRC.

3. Thread penetration length is that portion held in the main member, including the screw tip.

4. For connections with 15/32" thick plywood or OSB side members, allowable withdrawal design values, W, must be limited by the head pull-through design value of 130 lb.

Screw Spacing Requirements

Table with construction specifications for load to grain distances and spacings for Simpson Strong Tie SD connector stainless steel screws.

1. For SD9SS screws subject to axial loading only, use the following minimum dimensions: end distance = 1 3/4", edge distance = 3/4", spacing parallel to grain = 1 1/4", spacing perpendicular to grain = 3/4".

Allowable Shear Loads | Steel/Stainless-Steel Side Plate

Table showing shear load capacities for different sizes of steel members with stainless steel side plates.

1. Loads are given for CD = 1.00 and may be increased for load duration per the building code to CD = 1.60.

2. Stainless-steel side-plate thickness is 33 to 100 mil (20 –12 ga.)
